Bra Fit Guide

Find My CUUP Size
Start by putting on your best-fitting, non-padded, non-minimizing bra.
Remember to measure in inches.
Step 1: The Band

- With a measuring tape, measure around your ribcage directly below the wire of your bra.
- Ensure the tape is at the same level on your back, sides and front.
- Input that measurement into our size calculator in the "band" box.
Step 2: The Cup

- Loop the measuring tape around your back, just under your shoulder blades, then up around the fullest part of your bust
- Keep the tape level from end to end.
- Input that measurement into our size calculator in the "bust" box and calculate your size.

The measuring module above uses your body’s exact dimensions to recommend your CUUP size. The table below will estimate your size based on the bras in your drawer.
