Why does my bra band ride up in the back?

A bra band rides up when it's too loose. The band provides 80% of support and should fit snugly on the loosest hook. Try going down a band size (and up a cup to maintain fit). The band should stay level and parallel to the floor.

Why do my bra straps keep falling down?

Slipping straps can indicate: straps need tightening, you have sloped shoulders (try racerback or convertible straps), the band is too big causing straps to be set too wide, or the cups are too big pulling the bra down.

Why do my bra cups gap or wrinkle?

Gapping cups usually mean the cup is too big, or the cup shape doesn't match your breast shape. Try a smaller cup size, or a different style - shallow breasts need shallower cups, while projected breasts need deeper cups.

Why do I have spillage over my bra cups?

Spillage (double boob) means the cups are too small. Go up one or more cup sizes until all breast tissue is contained. Also check that you're scooping all tissue into the cups and that the underwire sits in your inframammary fold.

Why does my bra underwire poke or dig in?

Underwire poking can mean: the cup is too small (wire sits on breast tissue), the wire width doesn't match your root width, the bra is worn out and wires are warped, or the style isn't right for your shape. Try a larger cup or different wire width.

Bra Fit Problem Diagnoser – Fix Common Issues

What this tool does

Most fit problems have a specific cause and a specific fix. Tell it what is going wrong — band riding up, straps slipping, cups gapping or spilling, wires poking — and it explains why that happens and which size or style change resolves it. Several problems can be selected at once, and the suggested size changes are combined.

Common Bra Fit Problems & Solutions

Band Rides Up

Cause: Band is too loose

Fix: Go down a band size (and up a cup size to compensate). The band should be snug on the loosest hook.

Straps Slip Off

Cause: Sloped shoulders, straps too loose, or band too big

Fix: Tighten straps, try a racerback converter, or go down a band size.

Cups Gap

Cause: Cup too big or wrong shape for your breasts

Fix: Try a smaller cup size or a different cup shape (e.g., plunge vs full coverage).

Spillage Over Cups

Cause: Cup too small

Fix: Go up one or more cup sizes until all tissue is contained with no bulging.

Underwire Pokes

Cause: Cup too small, wire too narrow, or bra worn out

Fix: Try a larger cup, different wire width, or replace old bras.

Gore Doesn't Tack

Cause: Cups too small or close-set breasts

Fix: Go up in cup size, or try a plunge style with lower gore.
