Wondering why your new bra feels snug or comes up higher under the arms? Learn why a proper bra fit feels different at first, why marks are normal, and how to break in your bra the right way.
Why a Correct Bra Fit Feels Different
If your new bra feels snugger in the band, comes up higher under your arms, or rests more firmly under your breasts than you’re used to, don’t panic! That’s not a sign of a bad fit, it’s actually a sign you’re wearing the right size.
Most women have spent years in bras that are too big in the band and too small in the cup. When you finally put on a correctly fitted bra, your body isn’t used to being supported in those areas. It can feel strange at first, but that “different” feeling means your bra is doing its job.
Common Things You Might Notice
- A Snug Band: Your band should sit firmly around your ribcage, because that’s where 80% of your support comes from. A too-loose band will ride up, slip, and leave your shoulders carrying the weight.
- Higher Cups Under the Arms: A well-fitting bra contains all your breast tissue, including the tissue under your arms. So, it will be higher under the arm than you are used to. That’s a good thing. It keeps everything forward and lifted.
- Wires That Sit Right Under the Breast Root: Your underwire should rest exactly where your breast attaches to your ribcage, not floating on your breast tissue. This ensures proper lift and prevents discomfort.
Breaking In Your New Bra
Just like new shoes, a new bra takes some time to settle in. Here’s our recommended approach:
- Wear in increments for the first two weeks. Start with a couple of hours at a time and work your way up to full-day wear.
- Expect light marks when you take your bra off. Think of the marks left by your socks and leggings. Your bra is holding you snugly for support, but those impressions fade quickly.
- Adjust slowly. Over time, the fabric will mold to your body, and the snugness you feel at first will relax into long-lasting support.

When to Be Concerned
It’s normal to have most red marks fade within an hour or so, but if you’re experiencing pain, digging wires, or marks that don’t go away, that may mean you need an adjustment in size or style. That’s where our fit experts come in! Schedule a virtual fitting, and we’ll help troubleshoot the issue.
Final Thoughts
A proper bra fit may feel unusual at first, but that’s because your body is adjusting to real support. Once you break in your first correctly fitted bras, you don't have to do that with each new bra. All future bras are much easier to break in.
