Bra Types Explained: A Complete Style & Fit Guide

Most women in Bangladesh buy the same bra shape for years without ever asking whether it suits the outfit — or their body. The result is familiar: straps that slip under a wide neckline, cups that gape under a fitted kameez, or an underband that rides up by midday.

Bra shapes are not interchangeable. Each one is built for a different level of coverage, a different neckline, and a different kind of day. This guide from PTex breaks down every common bra type, what it works under, and how to pick the right band and cup — so your next purchase actually stays comfortable.

Bra Types by Shape

Shape refers to how much of the bust the cup covers and where the neckline of the cup sits. This is what determines whether your bra stays hidden under a given top.

Full-Cup Bra

The cup covers the bust completely, from the underwire to the top edge. This spreads weight across a larger surface, which reduces strain on the shoulders and keeps movement to a minimum. It creates a smooth, rounded line under clothing and is the most reliable choice for larger cup sizes.

• Wear it under: Kurtis, shirts, office wear, high and round necklines
• Best for: D cup and above, all-day wear, anyone who wants full coverage

Plunge Bra

The centre panel between the cups is cut low, forming a deep V. The cups angle inward, bringing the bust toward the centre. Coverage at the top of the cup is reduced, so it disappears under low or open necklines.

• Wear it under: V-necks, wrap tops, deep-neck blouses
• Best for: Small to medium busts, though supportive versions exist for fuller sizes

Balcony (Balconette) Bra

Straps are set wide apart and the cup neckline runs roughly horizontal, lifting from underneath rather than covering from above. Balcony and balconette are two names for the same shape.

• Wear it under: Square necks, scoop necks, boat necks
• Best for: Lift and a rounded shape without heavy padding

Demi / Half-Cup Bra

Covers roughly half to two-thirds of the bust, with a more open neckline than a full cup. Lighter coverage, but noticeably less support for fuller busts.

• Wear it under: Lower-cut tops, occasion wear
• Best for: Small to medium busts

Push-Up Bra

Padding is concentrated at the bottom and outer edge of the cup, angling the bust upward and inward. It changes the shape rather than simply supporting it.

• Wear it under: Fitted or lower-cut outfits where extra shape is wanted
• Best for: Adding volume and lift; less practical for long, hot days

Bra Types by Style

Style refers to construction and purpose — what the bra is built to do, rather than what shape it makes.

T-Shirt Bra

Moulded, seamless cups with light padding, designed to sit invisibly under close-fitting fabric. No seam lines, no texture showing through.

Bralette

Soft, unstructured, usually wireless and often made from lace or stretch fabric. Comfortable and easy to wear, but offers gentle support only.

Strapless Bra

Built with a wider, firmer underband to hold position without shoulder straps. Fit at the band matters more here than in any other style — if the band is loose, the bra will slide.

Non-Wired (Soft Cup) Bra

No underwire; shape and support come from the fabric, seams and elastic band. Easy to wear for long stretches, with a softer, more natural silhouette.

Sports Bra

Made to limit movement during activity, available in low, medium and high impact levels. Compression-style versions flatten and hold; encapsulated versions support each side separately and generally suit fuller busts better.

Nursing Bra

Cups unclip from the strap for feeding access, and the fabric accommodates changing size through pregnancy and after. Wireless versions are the usual recommendation for this stage.

Sleep Bra

Light, stretchy and wireless, made for gentle support overnight rather than shaping. Useful for anyone who finds sleeping without a bra uncomfortable.

Padded vs Non-Padded: Which Should You Buy?

This is the question that decides most purchases, so it's worth being clear.

Padding does not equal support. A non-padded bra with an underwire, a firm underband and a wide side wing will hold more securely than a padded bra with a loose band. For daily wear in warm weather, most women find a non-padded full-cup bra the more comfortable of the two.

Which Bra Goes With Which Neckline

Getting the Size Right

Most fit complaints are band problems, not cup problems. Measure before you order:

• Band: Measure snugly around the ribcage, directly under the bust. Round to the nearest even number.
• Cup: Measure loosely around the fullest part of the bust. Subtract the band measurement — the difference gives your cup.

Three quick fit checks once it's on:

• The band should sit level all the way round, not ride up at the back
• Two fingers should slide under the band — no more
• The centre panel between the cups should sit flat against the chest

Fasten a new bra on the loosest hook. Elastic relaxes with wear, and the tighter hooks are there to take up that slack later.

PTex Picks: Non-Padded Full Cup Lace Bra

If you take one thing from this guide, make it this pairing — a full-cup shape with non-padded cups. Full coverage and underwire support, without the extra heat of foam. PTex stocks it in two everyday colourways, in bands 32–44 and cups D–H, at Tk 499 each.

Both are cut from soft floral lace with unlined cups that follow your natural shape, a wide lace side wing for support, adjustable straps, a scalloped hem and a multi-row hook-and-eye back closure so you can set the band exactly where it's comfortable. Fabric is 85% nylon, 15% elastane.
