Fit Questions
Everything you need to know about finding your perfect fit.
Sister sizes share the same cup volume with different band and cup labels. Going up a band = going down a cup letter.
- Band: Firm on the loosest hook, parallel to the floor.
- Cups: Flush against your skin with no gaping or spillage.
- Center gore: Sits flat against your chest.
- Straps: Stay in place without digging in.
Go down one cup size (e.g. 32A to 32AA) while keeping the same band. Gaping cups = cup is too large.
Go up one band size and down one cup letter to keep the same cup volume. Example: 32A becomes 34AA.
First tighten the straps. If they still slip, your band may be too large - try going down a band size. Racerback styles are great for narrow or sloped shoulders.
When in doubt, size up in the band. Trust your cup measurement. If you're still unsure, reach out - we're happy to help.
This is completely normal. Fit the larger side - the cup on the smaller side will simply not fill out as much. Lightly padded styles help balance the silhouette.
