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.

Description

The DIM Generous 3983 B9O Bleu Forme bra offers a balanced combination of support, comfort and lightness, designed specifically for large busts.

It features underwires for stable hold and is unpadded, maintaining the natural shape of the bust with a comfortable feeling throughout the day. The top of the cups and the straps are made of semi-sheer tulle, a delicate detail that provides a feminine and visually light finish.

The cups include an inner mesh lining, which reinforces control and helps achieve a firm fit without pressure. It is a bra designed for everyday wear for women looking for comfort, style and reliable support in generous sizes.
