Your waist measurement

📏 Between sizes? Size up for a more relaxed fit — the support pouch works best with a little room to breathe.

Find a tape measure

A soft measuring tape works best — the kind used for clothing.

Measure your natural waist

Wrap the tape around your waist at the level you'd normally wear underwear — usually just above the hip bone.

Match to the chart

Find your measurement in the size chart. If you're between sizes, go up.

✓

Start with your normal underwear size. Ballbra follows standard sizing — no need to go up or down from what you usually wear.

✓

Between sizes? We recommend sizing up for a more comfortable fit and better pouch support.

✓

Prefer a firmer hold? Stick with your usual size — the support pouch works in both.

If the sizing isn't right, our 30 Day Comfort Guarantee has you covered. Full refund on your first pair, no questions asked.
