UK Fitting Guide & EU Conversion
Triumph is a German lingerie brand with over 135 years of heritage. As a European brand, Triumph uses EU sizing — which differs from UK sizes. This guide explains exactly how to convert between Triumph's EU sizing and standard UK sizes.
Does Triumph Use UK or EU Sizing?
Triumph primarily uses European (EU) sizing. This means:
Band Sizes (EU)
EU bands are measured in centimetres: 70, 75, 80, 85, etc. These correspond to UK sizes 32, 34, 36, 38, etc.
Cup Sizes (EU)
EU cup letters run differently after C. UK DD = EU E, UK E = EU F, UK F = EU G, and so on. The double letters (DD, FF, GG) don't exist in EU sizing.
UK to Triumph EU Cup Conversion
| UK Cup | Triumph EU Cup |

| B | B |
| C | C |
| D | D |
| DD | E |
| E | F |
| F | G |
| FF | H |
| G | I |

Example: If you are UK 34DD, your Triumph size is EU 75E.

Triumph Fitting Tips for UK Shoppers
Always convert your UK size to EU before ordering from Triumph — use our conversion table above.
Triumph bands tend to be true to size or slightly snug compared to UK brands. If you're between sizes, try the larger band.
Remember that EU cup sizes don't use double letters. UK DD = EU E, UK FF = EU H, etc.
If ordering online from Triumph UK, sizes are usually displayed with EU labels but UK equivalents are often shown alongside.
