Fit by product & style
Smoothie Spacer
Use the UK cup conversion and US band below. A molded spacer cup has its own shape; gaping or pressure can indicate a shape mismatch as well as a size issue.
Luxe Strapless Multiway
Check support with the straps removed before using another strap configuration. The band should stay secure during movement and the cups should contain the bust without spilling.
UK cup letters with US bands
Curvy Kate uses UK cup lettering on our cup-sized products. US DD/E becomes UK DD; US DDD/F becomes UK E. UK E is a different cup from US DD.

| DD / E | DD |
| DDD / F | E |

For example, US 34DDD/F corresponds to 34E in this cup comparison. A comparison is a starting point, not a promise of identical fit across brands. For labels beyond this chart, contact our team.
How to measure & check fit
Use a soft tape. Measure the fullest part of your bust, your natural waist and the fullest part of your hips, keeping the tape level without pressing into the body. Tables labeled body measurements refer to you, rather than the garment laid flat.
For bras, measure snugly directly below your bust and around the fullest bust in an unpadded bra. These measurements help our team assess a starting size; band methods and cup construction differ by style.
- The band should sit level and feel secure without restricting breathing.
- Cups should contain the bust without spilling or gaping, and wires should sit around breast tissue comfortably.
- Adjust straps without using them to compensate for a loose band. Check fit while sitting and moving.
