Common Bra Fit Problems and Solutions

Most bra fit problems trace back to one of two causes: an inaccurate band size or an inaccurate cup size. Fixing the band first resolves the majority of common complaints, including digging straps, riding-up bands, and cups that gap or spill.

Problem: The Band Rides Up

Cause: The band is too loose.

Solution: Re-measure your rib cage directly under the bust using the rib cage method and size down the band, adjusting the cup size accordingly.

Problem: Straps Dig Into Shoulders

Cause: The band is too loose, so the straps are carrying support they were not designed for. About 80 percent of a bra's support should come from the band.

Solution: Size down the band rather than tightening the straps further, which only treats the symptom, not the cause.

Problem: Cups Gap or Wrinkle

Cause: The cup size is too large for your bust.

Solution: Size down the cup while keeping the band the same, or use a sister size as a temporary adjustment.

Problem: Breasts Spill Out of the Cup

Cause: The cup size is too small.

Solution: Size up the cup while keeping the band the same. If the band also feels loose, re-measure both band and cup from scratch.

Problem: The Band Feels Too Tight or Leaves Marks

Cause: The band is too small.

Solution: Size up the band, adjusting the cup size to maintain the correct volume.

Problem: The Bra Feels Fine Standing Still But Not Moving

Cause: Often a band or strap issue that only shows up under motion. A snug band should stay in place through arm movement, not just while standing still.

Solution: Try the bra on and move — raise your arms, twist, and bend — before deciding on a final size.

Problem: I'm the Same Size I've Always Been, But My Bras Don't Fit

Cause: Bodies change due to weight fluctuation, exercise, hormones, or simply time, even without a major life event.

Solution: Re-measure every 6 to 12 months rather than assuming a size is permanent.

Frequently Asked Questions

Why does my bra hurt even though it is my usual size?

Bodies change over time, and a size that fit a year ago may no longer be accurate. Re-measure rather than assuming your usual size is still correct.

Should I fix a fit problem by adjusting the straps?

Only if the band itself already fits well. If the band is too loose, tightening the straps treats a symptom, not the cause, and the problem will return.

How do I know if it is a band problem or a cup problem?

A riding-up band, digging straps, or a band that feels loose points to a band issue. Gapping, wrinkling, or spillage in the cups points to a cup size issue.
