Learn how to measure your bust and underbust at home for a perfect bralette fit. Step-by-step guide with common mistakes to avoid.
Quick answer
Use a soft measuring tape to measure your underbust and full bust, then compare your numbers to the brand’s size chart. A bralette relies on stretch and band fit rather than cup volume, so accurate circumference measurements matter most.
Why bralette sizing differs from underwire bras
Bralettes don’t use cup-and-band sizing in the same way underwired bras do. Instead of a rigid cup that must match your bust volume exactly, a bralette depends on the stretch of its fabric and the snugness of its band. That means your underbust measurement becomes the primary anchor for choosing a size.
Because bralettes are designed for comfort and light support, a little give in the measurement is normal. But if your underbust falls between two sizes, it’s usually better to size down for a secure fit that won’t ride up. If you’re between bust measurements, size up so the lace or mesh doesn’t cut into your skin.
Step-by-step bralette measurement guide
- Measure your underbust: Wrap a soft measuring tape snugly around your rib cage, directly under your bust. Keep the tape level and snug but not tight. Exhale normally and record the measurement in inches or centimeters. Common mistake: pulling the tape too tight. It should feel like a firm hug, not a squeeze.
- Measure your full bust: Stand straight with your arms at your sides. Wrap the tape around the fullest part of your bust, typically across the nipple line. Keep the tape parallel to the floor and relaxed—don’t pull it taut. Checkpoint: make sure the tape isn’t slipping down at the back. Ask a friend or use a mirror to verify the tape stays level.
- Compare to the brand’s size chart: Every bralette brand uses its own sizing, so always check the specific chart for the style you want. Match your underbust measurement to the band size, then use your full bust measurement to confirm the fit within that band range. Common mistake: assuming your usual bra size will match. Bralettes often run smaller or larger depending on fabric stretch.
