Measure Yourself at Home

Watch to see how to measure yourself at home to get an accurate band and cup size measurement.

Band Measurements: First you need to find your band size; wrap a measuring tape snuggly around your back under your bust line. If your measurement ends in a fraction, round up or down to the nearest whole number. This is your band size. 

Bust Measurements: Next, you need to find your bust size to determine your cup size; wrap the measuring tape around the fullest part of your bust. If measurement ends in a fraction, round up or down to the nearest whole number. 

Cup Size: Then, simply subtract your band size from your bust size to determine your cup size. Every inch equals 1 cup size. For example; 1 inch = A cup, 2 inches = B cup, etc. That is all it takes to find your perfect fit!

Common Fit Issues

Solutions to all your bra problems, right here!

Band Riding Up

If your brand doesn't sit just below your shoulder blades, try tightening the band or loosening the straps. If that doesn't help, you need a smaller band.

Band Digging In

If your band is digging into your ribs, chest or back, try loosening the band. If that doesn't fix it, you need to go up a band size or try a wider band.

Straps Digging In

If your straps are digging in, try loosening them or switching to a bra with padded straps. If that doesn't help, your band — which should be doing most of the support work — is too big and it's time to downsize.

Slipping Straps

If your straps are sliding around or off the shoulders, they might be stretched out (which happens over time). Or you might be in the wrong cup size causing the straps to sit too wide and slip more easily.

Dropping Bustline 

If your bustline is pulling down, shorten your straps (but not so much they dig) and check your cups (there shouldn't be any gap if they're the right size). If you want even more lift, look to non-stretchy bras with firmer support and rigid straps.

Overflowing Cups 

If you're spilling out the side, top or bottom of your cups, it's time to trade up. Bigger cups will help keep your bust securely (and comfortably) contained.

Gapping Cups

If your cups are gapping a lot or a little, try a smaller cup size so they sit flush with your skin.

Bulging Sides 

If you're squeezing out the sides, your band is too small and confining your bust. Go up a band size or try a bra with more cup coverage.

Poking Underwires 

If your wire pokes, you might be in the wrong cup size. Too small can make the underwire too tight while too big can cause the wire to move around. Both lead to uncomfortable poking or prodding.
