How to Measure
1. Find your band size
Align a measuring tape directly under your bust, keeping it parallel to the floor. The tape should feel snug but not tight around your body.
Use the chart, find your band size.
Band Size / Measurement
1. Find your cup size
Wrap the measuring tape at the fullest part of your bust, keeping it parallel to the floor. The tape should fit comfortably around your body.
Subtract your band size from your bust measurement. This bust-band difference determines your cup size.
* If your bust measurement is 36” and your band size is 32, the bust-band difference is 4”, indicating a D cup.

Why is EBY sized differently from traditional bras?
EBY runs XS through 2XLDD instead of traditional band-and-cup sizing. Each size maps directly to what you already know. Use the chart above to find yours.
I'm between sizes. Should I size up or down?
Most EBY bras run true to size, but fit varies slightly by style. Check the Style Comparison chart above for specific recommendations before you decide.
Why do EBY bras feel snug at first?
EBY bras aren't pre-shaped to a generic body. They mold to yours over the first few wears. That initial snugness is part of how it gets to a custom fit, not a sign it's wrong.
