Zimmermann uses its own numeric sizing, which can be confusing the first time you shop the brand. The good news is that it is consistent and easy to translate once you know the system. Here is our fashion desk guide to Zimmermann sizing, the international conversions, and how the pieces actually fit.

How Zimmermann sizing works

Zimmermann sizes run on a numeric scale from 0 to 4, with a 0P petite option at the smaller end. A 0 is the equivalent of a UK 6, and each step up adds two UK sizes. So a Zimmermann 2, the brand’s most common size, lines up with a UK 10. Use the table below as your starting point.

Does Zimmermann run true to size?

As a rule, yes. Zimmermann is cut true to size with the considered proportion the house is known for, so your usual size is the right place to start. A few things are worth knowing. Lined and corseted styles can sit closer at the bust, so if you are between sizes on a fitted bodice, size up. Relaxed and tiered styles carry plenty of ease, so there is no need to size up for comfort. Swimwear is cut to be snug, as it should be, and softens a little once worn.

How to get the fit right

• Always check the size guide on the individual product page, since measurements vary by style.
• For a tailored line, take your true size. For a softer, more relaxed line, size up one.
• Petite frames should look at 0P and 0, while taller frames will find the maxi lengths carry beautifully.
• If a piece is fitted at the bust and you are unsure, our stylists are happy to advise before you buy.
