Triumph bra size guide
Triumph uses standard EU sizing. The band number is your underbust in centimetres, and cup letters run in a single unbroken sequence — no DD or DDD, just A, B, C, D, E, F and onward.
How EU sizing works
Measure your underbust snugly in centimetres and round to the nearest 5 — that's your band (e.g. 73 cm rounds to 75). Measure your bust at its fullest point; the difference between the two determines the cup, using roughly 2 cm per letter starting from A. This is the standard method used by most continental European lingerie brands, including Triumph, Hunkemöller, Chantelle and Sloggi.

Frequently asked questions
What sizing system does Triumph use?
Standard EU sizing — band in cm, with a single-letter cup progression (A, B, C, D, E, F...).
Is EU E the same as UK E?
No — EU E corresponds to UK DD. The two letter systems shift apart above a D cup.
How do I convert my UK size to Triumph (EU)?
Use the EU-UK converter, or measure your underbust in cm directly for the most accurate band size.
