What to Wear Under a Thobe for Comfort and Confidence

by Al Badr 04 Feb 2026

Wearing the right undergarments under a thobe ensures comfort, modesty, and a polished look. Key considerations include:

  • Undershirts: Opt for breathable fabrics like bamboo viscose, cotton, or micro modal. Skin-toned or grey undershirts work better under light-coloured thobes to avoid visibility, while V-neck or sleeveless options help maintain a neat appearance.
  • Lower layers: Sirwal trousers or 3/4 shorts provide ease of movement and coverage. Lightweight cotton or polyester trousers work well under light-coloured thobes, while thermal leggings are ideal for colder weather.
  • Fit and colour: Choose slim-fitting, neutral-toned undergarments to avoid bulk and visible lines. Proper fit ensures the thobe drapes smoothly without clinging or bunching.
  • Seasonal fabrics: Use natural, breathable fabrics like linen or bamboo blends for warm weather. For colder months, thermal layers in light, fitted designs provide warmth without affecting the thobe’s flow.

Selecting an Undershirt

A good undershirt does more than just sit beneath your thobe - it absorbs moisture, prevents clinging, and provides modest coverage. This layer ensures sweat doesn't seep into the outer fabric, eliminates visible body lines, and helps maintain a smooth, polished drape. For white or light-coloured thobes, an undershirt is especially important since these garments can become surprisingly see-through in bright sunlight. With these benefits in mind, it’s worth considering which fabric will suit your needs best.

Fabric Types to Consider

When choosing an undershirt, the fabric plays a major role in both comfort and functionality.

Bamboo viscose is a standout choice, combining a silk-like texture with excellent breathability. As Robert Owen Undershirts puts it:

The bamboo fabric has a smooth filament, just like silk and is highly breathable, so your skin stays cool. The fibre is moisture absorbing, so any sweat (or water vapour) is taken away from your skin and trapped before it can reach your shirt.

A blend of 95% bamboo viscose and 5% spandex offers four-way stretch, ensuring the undershirt retains its shape even after multiple washes.

Cotton is a classic option, valued for its softness and breathability. However, it can feel heavier, and repeated washing may leave it stiff. Micro modal, on the other hand, offers a lighter, smoother alternative with a luxurious feel against the skin.

For those who sweat heavily, moisture-wicking synthetics are a practical choice. These fabrics pull sweat away from your body, keeping you dry during physical activity or in humid conditions.

Colour and Neckline Options

The colour of your undershirt can make a big difference, especially under light-coloured thobes. White undershirts, while traditional, can create a noticeable contrast. Instead, opt for skin-toned, beige, or heather grey shades to maintain a seamless look. For darker thobes, black or grey undershirts are ideal.

The neckline is another important factor. A deep V-neck is perfect if you prefer leaving the top buttons of your thobe open, as it stays hidden beneath the collar. Meanwhile, a crew neck offers more coverage and works well with high-collared thobes.

In particularly hot weather, sleeveless vests or tank tops can improve airflow by eliminating sleeve lines. However, they provide less protection against sweat on the arms. These options are a modern twist on traditional undershirts like the Fanilla, adapted for today’s needs.

The Fanilla and Modern Alternatives

In Gulf traditions, the Fanilla is the go-to undershirt for wearing under a thobe. Typically pure white, it comes in either a tank top or short-sleeved t-shirt style. As Kosupa Travel explains:

Local men always wear an undershirt called 'Fanilla' which is pure white and mandatory under the thobe. This comes in tank top or short-sleeve t-shirt form, playing an important role in preventing skin and body lines from showing through.

While authentic Fanillas may be harder to find in the UK, modern alternatives bridge the gap between tradition and innovation. Many now feature advanced fabric technologies for better moisture control. UK retailers often stock fitted bamboo or micro-modal vests, and speciality stores frequently offer discounts on multi-packs.

For the best fit, choose a slim style that stays in place without bunching. Longer undershirts are especially useful, as they stay tucked in during movement or prayer, eliminating the need for constant adjustments. This ensures both comfort and a sleek, elegant appearance for your thobe.

Lower Body Undergarments

Once you've sorted a comfortable undershirt, it's time to focus on lower-body layers to complete your outfit. These layers are essential for maintaining modesty, comfort, and ease of movement. The right choice ensures your thobe drapes naturally, avoids clinging, and keeps outlines discreet.

Sirwal and Contemporary Options

The sirwal has been a traditional go-to for centuries. These trousers, with their deep cultural roots, are designed for comfort and practicality. As Grokipedia describes:

The sirwal... is characterised by a diamond-shaped crotch gusset for comfort, tapering ankles, and a drawstring or elastic waistband, typically made from breathable cotton or linen.

Typically crafted from cotton or linen, sirwal offer breathability and freedom of movement, while also staying true to tradition. Modern adaptations have introduced updated designs that enhance comfort without compromising modesty.

For a more contemporary take, 3/4 shorts are gaining popularity. Ending at mid-calf, these shorts often feature zip pockets and adjustable drawstrings for practicality. They're especially useful during prayer, as their length ensures modesty in various positions. As Al Aniq points out:

Wearing 3/4 shorts under your thobe adds an extra layer of coverage, which can be especially useful during windy days or whilst engaging in physical activities.

If you prefer full-length coverage, lightweight trousers made from thin cotton or polyester blends are a great choice. These are particularly effective under white or light-coloured thobes, where transparency might be an issue. For colder seasons, thermal long johns or slim flannel trousers provide warmth without adding bulk.

Standard underwear - whether cotton boxers, briefs, or moisture-wicking boxer briefs - remains a must under any of these options. They help prevent chafing and provide essential support.

Getting the Right Fit

Fit is key when it comes to undergarments. Loose, well-fitted layers with elastic waistbands allow for unrestricted movement without adding unnecessary bulk. As Alif Thobes notes:

A good inner layer helps your thobe fall nicely without clinging to the body or looking uneven.

Avoid heavy fabrics like denim or thick trousers, as these can create a bulky silhouette and restrict movement. Alif Thobes also warns:

Choosing thick and heavy trousers is also not ideal because they won't let the thobe fall freely.

Colour coordination plays a big role in achieving a polished look. For white or light-coloured thobes, stick to white, beige, or skin-toned undergarments to keep them invisible. Darker thobes are more forgiving, allowing for black or grey layers. Always check your thobe against light to ensure your undergarments don’t show through.

Finally, consider the length of your lower layers. Knee-length or 3/4 options provide excellent coverage while preventing the hem of the thobe from clinging to your legs when sitting or bending.

Choosing Fabrics for Different Weather

The fabric of your undergarments plays a key role in staying comfortable throughout the year. What works well in summer might not provide enough insulation in winter, and vice versa. To help you stay comfortable and maintain modesty under a thobe, let’s explore the best fabric choices for both warm and cold weather.

Warm Weather Fabrics

When the heat rises, natural and breathable fabrics are your go-to. Cotton is a summer favourite because it absorbs moisture and helps manage perspiration effectively. Another standout is linen, which is perfect for humid conditions. Its airy structure allows heat to escape, and as Edouard, Founder of G-Heat, points out:

Linen is ideal for people prone to skin irritation. Its softness and antibacterial properties soothe sensitive skin.

For a touch of luxury and practicality, silk offers excellent temperature control. Romane Benderradji, Communications Manager at G-Heat, notes:

Silk is considered the most breathable fabric. Its structure and lightness make it highly breathable.

Modern bamboo-viscose blends are another great option, offering natural antimicrobial properties that help resist odours. Even tropical-weight merino wool (around 220 g/mΒ²) can handle the heat, thanks to its tightly twisted yarns that create air channels to release warmth - even at temperatures as high as 38Β°C. On the other hand, steer clear of pure polyester, acrylic, or nylon base layers, as these materials tend to trap heat, bacteria, and odours.

Cold Weather Layering

Winter calls for thermal layers that provide warmth without adding unnecessary bulk. A lightweight thermal or cotton long-sleeve top works perfectly as a base layer, keeping you warm while allowing your thobe to flow naturally. For the lower body, thermal leggings or compression pants in neutral tones are excellent for retaining heat. As Thobez.co.uk aptly advises:

A lightweight thermal or cotton long-sleeve top is an excellent choice for insulation without bulk.

To avoid discomfort, opt for "slim fit" or "fitted" thermal garments, which prevent bunching under your thobe. Flannel shirts or long johns also add warmth, and pairing white or skin-toned thermals with light-coloured thobes ensures your layers remain discreet. Even in winter, moisture-wicking base layers are handy for active individuals, helping to manage sweat during daily routines or visits to the masjid.

Getting the Fit Right

How your undergarments fit plays a huge role in maintaining the sleek, elegant flow of your thobe. A proper fit ensures both comfort and a polished appearance. Slim-fit layers are an ideal choice - they stay in place and prevent any awkward bunching. On the other hand, oversized undergarments can create a bulky, uneven look. As Alif Thobes puts it:

A good inner layer helps your thobe fall nicely without clinging to the body or looking uneven.

The key is to pick lightweight, slim-fitting layers that don’t leave marks or disrupt the smooth drape of your thobe. This attention to fit naturally leads to another important consideration: keeping your undergarments discreet.

Preventing Visible Lines

To maintain a clean, polished look, your undergarments should remain invisible. Seamless designs and smooth fabrics help achieve this. For white or light-coloured thobes, skin-toned or beige undershirts are a better choice than white ones, as they blend more naturally with your skin tone and avoid creating noticeable contrasts. A quick check in natural light can help ensure nothing is visible through your thobe.

For the lower body, boxer briefs or snug briefs are preferable to loose-fitting boxers. Al-Haq Thobes advises: "Make sure the panties fit snugly to prevent bunching or lines from showing". For the upper body, a V-neck undershirt stays hidden beneath the collar, while sleeveless vests eliminate sleeve lines altogether. These subtle adjustments ensure your undergarments support the thobe’s flow without drawing attention.

Comfort Without Bulk

When it comes to comfort, 3/4 length shorts (sirwal) or lightweight cotton trousers are excellent choices. They offer modest coverage while remaining breathable and flexible, particularly during prayer.

Avoid thick or oversized garments, which can interfere with the thobe’s natural drape. Alif Thobes warns: "Choosing thick and heavy pants is also not ideal because they won't let the thobe fall freely. Oversized shirts can bunch up and create an uneven look". Instead, go for breathable, moisture-wicking fabrics in slim-fit designs. These options move with your body and keep you comfortable all day, while allowing your thobe to maintain its graceful silhouette.

Undergarment Choices for Men and Women

When it comes to undergarments, comfort and modesty are shared priorities for men and women. However, their layering choices often differ to accommodate lifestyle needs and preferences.

Men's Options

For men, a breathable cotton undershirt or vest is a practical starting point. Sleeveless options work well in warm weather, while short-sleeved designs provide added modesty when needed. Slim-fit styles are a smart choice since they prevent bunching and keep lines discreet under outer garments. As Shabab Al Yola highlights:

"Proper underpants (briefs, boxers or boxer briefs) support the groin and prevent chafing."

Traditional sirwal trousers are another option, offering freedom of movement and a nod to cultural heritage. For a more modern approach, 3/4 length shorts have become a popular alternative. These shorts provide modest coverage, are lightweight, and often include practical features like zip pockets. Plus, they’re machine washable, making them ideal for active lifestyles. In cooler weather, slim thermal layers can add extra warmth, while moisture-wicking fabrics are a great choice for those who tend to sweat.

Just as men prioritise practicality and style, women’s undergarment choices focus on achieving comfort, modesty, and ease of movement.

Women's Layering Approaches

For women, layering undergarments involves balancing full coverage with breathable comfort. A long-sleeved top or a knee-length shirt paired with loose-fitting trousers or a lightweight long skirt creates a modest and comfortable base under a thobe. The sirwal is also a versatile option, with its loose fit historically favoured by Ottoman and Bedouin women for ease of movement and practicality.

Natural fibres like organic cotton, linen, or muslin are excellent for regulating temperature and wicking away moisture. For light-coloured thobes, skin-toned or beige underlayers help maintain modesty by reducing transparency. During the colder months, thermal leggings or thin compression trousers can provide warmth without interfering with the elegant drape of the thobe.

The key is to create layers that offer both comfort and complete coverage, allowing freedom of movement whether standing, sitting, or bending during prayer.

Conclusion

The right undergarments can make a thobe feel more comfortable, fit better, and look effortlessly elegant. It all starts with breathable fabrics like organic cotton or moisture-wicking materials that help regulate body temperature and reduce irritation. Whether you prefer the traditional sirwal or modern 3/4 shorts, the focus remains on achieving comfort, modesty, and ease of movement.

When choosing fabrics, consider the local climate. In warmer weather, sleeveless vests enhance airflow and keep you cool, while thermal underlayers are ideal for colder months, providing warmth without adding unnecessary bulk. Colour also plays a key role - skin-toned or white undergarments work best under light-coloured thobes, ensuring modesty and avoiding visible lines, especially in bright sunlight.

Comfort and cultural expectations go hand in hand, helping you feel confident while respecting proper awrah coverage. As Alif Thobes puts it: "A great thobe experience starts from the inside". Whether for daily activities or prayer, these choices are often guided by cultural practices and religious considerations. Modern options like 3/4 shorts with zip pockets blend practicality with tradition, making them a versatile choice for both formal events and everyday wear.
