Small Boobs, Big Boobs, How should your bra fit?

Whatever the size, the actual mechanics of a well-fitting bra don't change. Here's how to check each part, from smaller busts to fuller ones.

The Band

The band supplies most of a bra's support and should stay level all the way around, without riding up in back. It should feel comfortably snug, stretching slightly with wear over time.

The Center Gore

The center gore is the section between the cups, and it should lie flat against the chest. If it lifts off the chest wall, the band is likely too large, the cup too small, or both.

The Cups

Smaller busts should look for cups without extra fabric or gaping — loose fabric usually means the cup is too big. Fuller busts should look for cups that fully contain the breast tissue without spillage over the top or sides — spillage usually means the cup is too small.

Wire-Free Support

A wire-free bra can follow the body's natural shape while still providing real support, without the pressure points an underwire can create.

The Straps

Straps should be fully adjustable and shouldn't be doing the main work of holding the bra up — that's the band's job. If straps are digging in or need constant retightening, the band is often too loose; sizing down the band and up the cup usually fixes this.

Getting an Accurate Size

All of this starts with an accurate measurement. Measure the rib cage directly under the bust for band size, and the fullest part of the bust for the bust measurement — the difference in inches gives the cup size. See BRABAR's rib cage measuring method for the full walkthrough.

Frequently Asked Questions

How should a bra band fit?

Level all the way around, without riding up, and comfortably snug rather than tight.

What does it mean if the center gore doesn't lie flat?

Usually the band is too large, the cup too small, or both.

What if straps keep digging in or slipping?

The band is likely too loose. Sizing down the band and up the cup usually resolves this, since the band — not the straps — should carry most of the support.
