Finding a Bra That Actually Fits

Most bra discomfort comes from a band that’s too loose or cups that are the wrong size. A few checks in the fitting room fix most of it.

Remember this

1. The band does most of the supporting, so it should be snug and level.
2. Cups should lie smoothly without gaps or spilling over the edges.
3. Fasten a new bra on the loosest hook so you can tighten it as the band stretches.
4. Sister sizes keep the same cup volume on a different band size.

A bra that fits feels like it isn’t there. One that doesn’t makes itself known all day. Here’s how to tell the difference.

How fit works

A bra size has two parts:

• the band size, a number that relates to the measurement around your ribcage, just under your bust
• the cup size, a letter that reflects the difference between your band and bust measurements

Sizing systems vary between brands, so treat any size as a starting point and check the fit itself.

The fit check

Try the bra on the loosest hook, adjust the straps and lean forward slightly to settle into the cups. Then check:

1. Band: snug and level all the way around, not riding up at the back. You should be able to slide two fingers under it, but not much more.
2. Cups: smooth, with no gaps at the top or sides and no spilling over the edges.
3. Center: on an underwire bra, the center piece should lie flat against your breastbone.
4. Wires: they should sit on your ribs around the breast tissue, not on it.
5. Straps: they shouldn’t dig in or slip off. If you’re tightening them a lot to get support, the band is probably too loose.

Try this

Raise your arms and twist side to side in the fitting room. If the band moves up or the wires lift away, try a smaller band.

Sister sizes

If the cups fit but the band is too loose, go down a band size and up a cup letter, for example from 36C to 34D. The cup volume stays about the same. Going up a band size and down a cup letter works the other way.

When to replace

Bands stretch with wear and washing. When even the tightest hook feels loose, or the band rides up, it’s time. Rotating between a few bras helps each one last longer.

For workouts, a regular bra isn’t enough support; see choosing a sports bra. And because sizes differ between brands, it helps to know why your size changes from store to store.

You asked

Q: How do I know my size changed?

A: Signs include a band riding up your back, straps digging in, gaps or overflow in the cups, or wires sitting on breast tissue. Weight changes, pregnancy and hormones can all change your size.

Q: Should I get professionally fitted?

A: A fitting can be a helpful starting point, but sizes vary between brands, so check the fit of each bra yourself rather than relying on one number.

Q: How should I wash bras?

A: Follow the care label. Hand washing or a gentle cycle in a mesh bag, then air drying, helps the elastic last longer.
