How is the size worked out?

Measure around your ribcage, just under the bust. That figure plus 15 is your European band size: 75 cm gives a 90 band, which is a UK 34.
Measure around the fullest part of your bust.
Subtract the first measurement from the second. That difference is your cup: 15-16 cm is B, 17-18 cm is C, 19-20 cm is D…
Put the two together: 75 cm underbust and 92 cm bust is a 17 cm difference, which makes a 90C in European sizing — a UK 34C.
