Sézane Size Guide

The French label, Sézane, has become synonymous with Parisian style over the last 10 years. With stunning silhouettes, luscious fabrics, and beautiful neutral tones (with pops of color here and there!), the French brand has become a favorite of mine over the last couple of years. Every piece Sézane releases is better than the next and my collection has been growing quite rapidly. I just can’t seem to say no! Since it is a French brand though, sizing can be tricky, especially when you first start adding their pieces to your wardrobe. To make it easier to shop the brand, I’m sharing a full Sézane size guide.

An Introduction to Sézane

Founded in 2013 by Morgane Sézalory, Sézane is a sustainable brand that is committed to high-quality clothing, shoes, and accessories that you’ll have for years. Over the last 10 years, Sézane has also supported countless charities and various communities. If you’re looking for a brand that makes your every day feel a little more elevated, while doing good, you’ll love Sézane.

How Does Sézane Sizing Run?

Sézane is a French brand, which I find to run smaller than American brands. For the most part, I size up in but they do have a handful of items that run larger, in which I take my regular size. 

Every product on the Sézane website also includes a size guide which includes a link to their size chart (below) and a note on how the piece runs and whether you should size up or down if you’re in between. To avoid having to constantly exchange pieces, I can’t recommend ordering different sizes or taking an accurate measurement.

My Usual Sizing

I usually wear a size 10/L in clothing and in Sézane, I typically wear my regular size. There are a few exceptions to this, though! When it comes to sweaters, I wear a size medium. And occasionally, I will size up for more space in the bust.

I cannot recommend purchasing a soft tape measure enough! Ever since I got one and learned what my measurements are, it makes ordering clothing online so much easier. I now only return clothing because I don’t like the style versus the wrong sizing!

Where to Shop Sézane

In addition to shopping online on their website, you can also shop Sézane at one of their locations in Paris, and across the United States. If you’re shopping online, keep purchases below $200 and $800 to save on shipping costs and avoid customs fees.

My Favorite Pieces from Sézane

Sézane has so many incredible pieces, making it hard to pick favorites. Truly every piece they launch is better than the next! I’ve slowly been building my Sézane collection and these have been my favorite and most worn pieces.

Max Shirt

This is my favorite oversized button-down and easily one of my most-worn pieces from Sézane. I own it in both white and denim, and love how effortlessly it pairs with everything from jeans and trousers to skirts and shorts. It has a relaxed, oversized fit, and I wear a size 10.

Morgane Necklace

Sézane has such beautiful jewelry, and this necklace has quickly become one of my most-worn accessories. The colorful stones make it feel special, but it’s still incredibly easy to style with everything from a simple t-shirt to a dress. It’s one of those pieces that instantly adds a little something extra to an outfit!

Clyde Coat

This is an absolute favorite trench coat of mine for both fall and spring. It has a classic, slightly oversized silhouette that makes it easy to layer over sweaters and button-downs, and it instantly elevates even the simplest outfit. I wear a size 8, which gives me the perfect relaxed fit with plenty of room for layering.

Emilie Cardigan

My inaugural Sézane piece, the Emilie Cardigan is thick and cozy, exactly how a winter sweater should be. Like most of Sézane’s sweaters, this one does run large but I went with my regular size (medium) so I could layer it over t-shirts and button-ups, while also achieving that perfectly oversized look when wearing it by itself. 

The Emilie Cardigan is on the chunkier side, so keep that in mind as well when deciding on what size to order!

Martin Trousers

If you’re in the market for a great pair of trousers for the cooler months, these ones from Sézane are the best! They are a wool blend (70% wool, 30% Polyamide) trouser with a straight wide-leg silhouette, perfect for cooler temperatures.

The Martin Trousers are also great for travel. Since they are 70% wool, they don’t wrinkle easily.

Gaspard Cardigan

The Gaspard Cardigan is a Sézane staple and for good reason. It’s cozy, comes in a bunch of colors, and can be worn with the buttons in the front or back! It does run a little big so if you’re in between sizes, I would size down. I have this cardigan in light beige and wear a size medium (my true size). I could easily do a small for a more fitted look!

Conrad T-Shirt

I recently ordered the Conrad T-Shirt on a whim and can’t believe I haven’t purchased one sooner. It’s the perfect weight, is 100% organic cotton (super breathable!), and is great for layering. I wear my regular size in this (medium) and comes in several colors. I have it in black but I need to order it in white and navy next

Amiel Jumper

The Amiel Jumper is one of my favorite sweaters from Sézane. It’s cozy, it’s soft, and it comes in the most gorgeous colors. I have the ice blue color, which you can see in this Reel, but I am eyeing the red and hope it comes back in stock! The fit is on the loser side, too. I would even go as far as perfectly oversized but if you want a more oversized look, size up. I went with my true size for a looser, but not too oversized, fit.

Milo Classic Bag

This bag is one of those timeless pieces that makes every outfit feel a little more polished. I love its structured silhouette, vintage-inspired details, and versatility. It’s the perfect size for everyday essentials and can easily be dressed up or down, making it a beautiful investment piece I know I’ll carry for years.
