How to Know If Your Bra Fits

5 min read

Most women find out their bra doesn't fit the same way — straps that won't stay up, a band that rides up in the back, or underwire that digs in by noon. Here's what your bra is trying to tell you.

The Band Is Doing All the Work

Your bra band should provide 80% of your support. If you're adjusting your straps every hour to compensate, the band isn't tight enough. You should be able to fit two fingers under the band — not four. A band that rides up means you need a smaller band size (and likely a larger cup to compensate).

The Cup Is Overflowing or Gaping

Spillage at the top or sides means the cup is too small. If the cup fabric wrinkles or gaps away from your body, it's too large. Both cause discomfort and poor posture over time.

The Underwire Sits Wrong

The underwire should sit flat against your ribcage, not on breast tissue. If it lifts off your chest at the center or digs into your sides, the cup or fit is off. This is one of the hardest problems to self-diagnose — which is why a professional fitting matters.

The Straps Leave Marks

Straps shouldn't dig in. If you have deep grooves by end of day, your straps are carrying too much load because the band is too loose. The fix is usually a smaller band, not looser straps.

What to Do About It

An in-person fitting at Karnation takes about 15 minutes. We measure, try several styles, and find the combination that actually works for your shape. No guessing. No awkward self-measuring at home.

We've been fitting women in Twin Falls for 30 years — including women who've never been properly fitted, women who had mastectomies, and new moms who need nursing support. Every body is different, and every fitting is private and judgment-free.

Stop guessing. Come in and find out what a bra that actually fits feels like.
