Size Guide

Finding your two sizes

Every Bielline dress asks for two sizes: one for your top, one for your bottom. Five minutes with a soft measuring tape is all you need, and you only need to do it once.

How to measure

Wear light clothing or measure over undergarments. Keep the tape snug, not tight.

For your top size

B

Bust: around the fullest point, tape parallel to the floor.

S

Shoulder: from shoulder point to shoulder point, across the back.

For your bottom size

W

Waist: around the narrowest point, usually just above the navel.

H

Hip: around the fullest point, roughly 20 cm below the waist.

Charts reflect our current grading and may be refined by up to half an inch as each capsule enters production.

Between sizes?

For the top, choose the size matching your bust: the shoulder can carry ease, the bust cannot. For the bottom, choose the size matching your hip.

If your measurements sit between sizes in both places, size down for a closer silhouette, size up for ease. Our fabrics drape; they do not cling.

Still unsure?

Write to us at hello@bielline.com with your four measurements and the dress you have in mind. A fit note comes back within one business day, from a person, not a bot.

Every dress is covered by our Fit Guarantee. If we make an error in production, we remake or refund in full.
