Elomi Size & Fit Guide
Find Elomi sizing for bras, panties and swimwear. Keep your US band number for cup-sized bras and swim tops, compare UK cup letters, and select briefs or bikini bottoms independently using their exact garment labels.
Fit by product & style
Matilda, Morgan & Charley
Keep your US band and choose the UK cup below. Plunge, full-cup and molded spacer designs give different coverage and shape.
Swim tops & tankinis
Use the UK cup conversion for bra-sized swimwear. A combined H/HH option is the pair offered on that exact top, not a panty size.
Briefs & swim bottoms
Choose the separate bottom label from waist and hip fit. Numeric 12–24 garment labels are not bra bands; ask us to confirm the numeric sizing convention and measurements for that exact style.
UK cup letters with US bands
Elomi 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.
| Familiar US cup | UK cup to select |
|---|---|
| A | A |
| B | B |
| C | C |
| D | D |
| DD / E | DD |
| DDD / F | E |
| G | F |
| H | FF |
| I | G |
| J | GG |
| K | H |
| L | HH |
| M | J |
| N | JJ |
| O | K |
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.
