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.

L

Hollow to Hem: from the hollow at the base of your throat straight down to where you want the hem to fall.

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.

Between sizes?

For the top, choose the size matching your bust. 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.
