Bra Fit and Cup Size Guide
Band, cup, support level, and the right bra for the right day
Bra sizing works best when you understand what each part of the size actually means. The band should sit firmly and level across your back because the band carries most of the weight and provides the real support. The cups should fully contain the bust without cutting in, leaving gaps, or creating spillage near the sides or centre. Cup size is not a fixed “small or large” label. Cup size is simply the difference between your bust and underbust measurements, which is why the same cup letter can look different across different band sizes. When the fit is correct, you should feel lifted and supported without having to constantly adjust straps or pull the band down.
A good fit also depends on the bra type. A smooth everyday bra behaves differently from a bralette, and a sports bra is built with a different purpose entirely. Use the types below to match the bra to your outfit and lifestyle.
T Shirt Bra
This is the everyday bra designed to disappear under clothing. The cups are usually smooth and lightly structured to prevent lines under fitted tops. Choose a t shirt bra when you want a clean silhouette for daily wear, office outfits, and occasions when your clothing is close to the body.
Non Padded Bra
Non padded bras feel lighter and more breathable because they avoid added foam. They are ideal when you want comfort and a natural look. Many people prefer this style for long wear days, warmer weather, and situations where a softer feel matters more than extra shaping.
Lightly Padded Bra
Light padding offers gentle shaping and nipple coverage without heavy volume. It can be a great middle ground for everyday wear because it feels supportive while still staying lightweight. Choose this when you want a slightly smoother look under clothes.
Push Up Bra
Push up bras are designed to lift and enhance cleavage. They use padding placement and cup construction to create a more pronounced shape. Choose this style for low necklines, special occasions, and outfits where you want a stronger lift and a more defined silhouette.
Bralette
Bralettes focus on comfort and softness. They are typically wire free and flexible, making them ideal for relaxed days, travel, and layering under casual outfits. A bralette can be your best choice when you want gentle support without the feel of a structured bra.
Wireless Bra
A wireless bra gives you a more secure everyday feel than a bralette while still avoiding underwires. It is a strong option for all day wear, especially if you prefer comfort but still want a stable fit and a defined shape under clothing.
Balconette Bra
Balconette bras create a lifted shape with a wider neckline. The straps sit wider, and the cups typically give a flattering open top look. This style works well with square neck and wide neck outfits where you want lift and a clean neckline.
Strapless Bra
Strapless bras are made to stay put without shoulder straps, which means the band and grip details matter even more. This style is ideal for off shoulder outfits and special dresses. Make sure the band is firm and the cups contain well, because that is what prevents slipping.
Sports Bra
Sports bras are built for movement and impact control. They reduce bounce and provide stability during workouts. Choose a low support sports bra for yoga and walking, medium support for gym sessions, and high support for running or high impact activity.

Panty Fit and Style Guide
Coverage, rise, and how to choose the right cut
The right panty size should feel smooth and secure, never tight or restrictive. A good fit stays in place throughout the day, prevents chafing, and avoids bunching under clothes. Hip measurement is the best way to choose sizing because it reflects the part of the body the garment needs to sit on comfortably. Style matters too. Some styles are ideal for daily comfort, while others are designed specifically to reduce visible lines or provide more coverage for long wear. If your panty rides up, rolls down, or leaves marks at the waist, you usually need a better fit, a softer waistband, or a style with a different rise.
Bikini
Bikini style offers a balanced fit with comfortable coverage. It works well for everyday wear and pairs easily with most outfits. Choose bikini when you want a reliable daily option that feels secure without being too high rise or too minimal.
Hipster
Hipster sits lower on the waist and provides wider side coverage. It is a great match for low rise bottoms and modern silhouettes. Choose hipster when you want a sleek fit that feels stable around the hips.
Boyshorts
Boyshorts offer fuller coverage and are often preferred for lounging and long wear. This style can help reduce ride ups because it covers more area on the hips. Choose boyshorts when comfort and coverage are your priority.
Thong
Thong is designed to reduce visible panty lines under fitted clothing. It is ideal for dresses, leggings, and body hugging outfits. Choose thong when you want minimal lines and a cleaner finish under clothes.
High Waist
High waist styles sit higher and offer a smoothing feel with supportive coverage. Many people prefer this style with dresses, high rise bottoms, and when they want a more held fit at the waist. Choose high waist when you want more coverage and a secure feel.
Seamless
Seamless panties are built to sit flat under clothes and reduce lines. They are a strong choice for fitted outfits and long days when you want a smooth finish. Choose seamless when you want comfort and a clean look under clothing.
Brief
Brief styles offer full coverage at the back with a secure fit. They are ideal for everyday comfort and are often preferred when you want a stable, no fuss fit for long hours. Choose briefs when coverage and comfort matter most.
| Size | Hip Measurement |
| Extra Small | 33 to 34 inch |
| Small | 35 to 36 inch |
| Medium | 37 to 38 inch |
| Large | 39 to 40 inch |
| Extra Large | 41 to 42 inch |
Sleepwear Fit and Fabric Guide
Comfort that supports deeper rest
Sleepwear should feel effortless. The best nightwear is the kind you do not notice once you are in bed. Fit matters because tight waistbands or restrictive bust and hip areas can interrupt sleep and create pressure points. Fabric matters because the body temperature changes at night, and a breathable, soft material helps you stay comfortable. If you tend to feel warm at night, lightweight breathable fabrics make a visible difference. If you feel cold, a slightly heavier knit or layering friendly set can help. Choosing the right material is just as important as choosing the right size.
Cotton Nightwear
Cotton is breathable and skin friendly. It works well for daily sleepwear, warm climates, and anyone who wants a classic soft feel that does not trap heat.
Modal and Viscose
These fabrics are known for a softer, smoother touch and a beautiful drape. They feel lightweight on the skin and are often preferred when you want a premium comfort feel.
Satin Feel Sets
Satin style sleepwear feels smooth and light. It is often chosen for a more elevated look and a gentle feel on the skin. Fit should be relaxed so it does not restrict movement.
Relaxed Fit Matters
A relaxed fit helps avoid waistband marks and improves comfort during sleep. If you are between sizes, a slightly roomier fit often feels better for rest.
Soft Waistbands
Look for waistbands that sit flat and do not twist. A softer waistband improves comfort during long wear and reduces pressure around the waist.
| Bust | Waist | Hip | Size |
| 32 to 34 | 24 to 27 | 35 to 37 | Small |
| 34 to 38 | 27 to 30 | 37 to 41 | Medium |
| 38 to 42 | 31 to 35 | 41 to 45 | Large |
Swimwear Fit and Style Guide
Support in water, stability on movement
Swimwear is designed to feel snug when dry because fabric relaxes slightly when it becomes wet. A fit that feels slightly secure on land often becomes the perfect fit in water. The purpose of a good swim fit is to maintain coverage, support, and shape retention while you move. Fabric choice also matters. Chlorine, salt water, and sun exposure can affect elasticity, which is why good swimwear focuses on stretch recovery and stability.
Bikini Top
Bikini tops come in different coverage levels. Choose a more structured top when you want better lift and stability, especially for swimming or active beach days.
One Piece
One piece swimwear offers more coverage and a secure feel. It is often preferred for swimming, travel, and when you want a more held fit through the body.
High Support Swim
Some swim styles are designed with stronger underband support and better containment. This helps the garment stay stable during movement and water activity.
Stretch Recovery
Swim fabrics should bounce back after use. Good stretch recovery means the garment keeps its shape after repeated water exposure.
Secure Fit Tip
If the suit feels slightly snug when dry, that is usually correct. If it digs in painfully or restricts breathing, sizing needs adjustment.
| Underband | Overbust | Size |
| 25 to 26 | 30 to 31 | Extra Small |
| 27 to 28 | 32 to 33 | Small |
Activewear Fit and Support Guide
Comfort, compression, and movement
Activewear should feel supportive and stable while still allowing full movement. A good fit stays in place when you bend, stretch, or walk. If activewear is too tight it can restrict movement and feel uncomfortable over time. If it is too loose it may ride up, shift, and distract you during activity. The right sizing helps reduce friction and improves comfort throughout workouts. Fabric matters here too. Performance fabrics are built to handle sweat, dry faster, and maintain shape through repeated wear.
Yoga and Low Impact
Choose a flexible fit with light support. Comfort and stretch matter more than strong compression for slower movement sessions.
Training and Gym
Medium support activewear helps you feel secure during strength training and regular gym sessions while still allowing movement.
High Movement Days
On running or high activity days, stability matters. Choose a fit that stays in place and supports movement without shifting.
Moisture Control
Performance fabrics help manage sweat and keep you comfortable. Look for materials that dry quickly and maintain softness.
Comfort Fit Tip
If you are between sizes, consider your preference. A closer fit feels more supportive while a slightly relaxed fit feels more breathable.
