A Guide To Sézane Sizing

Guide To Sézane Sizing

One common question I receive is about Sézane sizing and how the clothes fit? Today, I will provide a guide to Sézane on the sizing of the items I own by the clothing brand.

Who Is Sézane

Sézane is a French brand that I first discovered back in 2017 when I was googling French clothing brands. I ordered my first sweater from them and instantly fell in love with the brand. I have continued to add more and more pieces from Sézane each year.

The idea behind Sézane is to create high-qual­ity, perfectly-cut pieces that can be worn forever. Sèzane was born in Paris & craf­ted using the exper­t­ise of the best ateliers.

The quality of each item is some of the best I’ve ever worn and the pieces I first bought back in 2017 are still just as beautiful today. You might spend a little more on each item but they are without a doubt worth the investment.

Sézane releases a seasonal collection 4 times a year and once a month releases a smaller curated capsule collection. The pieces are timeless, will outlive any trend, and are also eco-friendly.

Make sure to sign up for the newsletter because you will always be notified ahead of time about the upcoming lookbook. I actually look forward to receiving emails and notifications from Sézane so I know what to put on my wishlist. You can also download the app to get firsthand looks before anyone else.

Certain items are considered Sézane essentials, and these items tend to always be in stock. Other items which are more seasonal will go quick so if you see something you like, you should probably grab it quickly.

There is only one U.S. location in New York and the rest are located in France and London. I have been lucky enough to visit both the New York and Paris locations.

Size Guide

Sézane provides a handy sizing guide listed on each page you can reference that shows French sizes converted to U.S. sizes. For the most part, I take my normal size in most of their items. However, with some items specifically the eyelet tops and sweatshirts, I will always go up a size. For reference, I am a 5ft. 5 1/2 inches, size 6 and small in U.S. sizes.

They do provide descriptions of each item and give advice on sizing. If your order is over $200 U.S. dollars you qualify for free shipping. I always recommend if you are unsure or if this is your first time ordering Sézane, maybe order two sizes and return whichever one doesn’t work. Sézane always offers free returns and they rarely have any kind of sale.

You can also see this post here which shows all the Sèzane best sellers I have and sizing for those pieces as well.

Sèzane tops are among some of my favorite because they are so classic and timeless. A few of my favorite tops I am loving right now are the Angela and the Lilo. For Summer I will be wearing my favorites with skirts and clogs. I wear a size 6 in tops or a 38 in European sizing.

One of my favorite Sézane tops would be this Marinière in Navy. The top has a boat neckline with 3/4 sleeves and 4 buttons that go up each side of the top. I am wearing this in a Medium for a more oversized look but if I ordered again, I would order a small for a more tailored look. This is a quintessential French woman’s top.

When I saw this cafe creme sweatshirt I need I immediately needed to have this. This was my favorite drink in Paris and Sézane sweatshirts are always nice and cozy. I always size up in the sweatshirts because they tend to run a little small. This is a medium and fits just right.

The Tomboy shirt is probably the most perfect button-down that I would love to own in every color available. It’s hard to find a great button-down that’s thick enough yet comfortable to wear all day. You can feel the quality in this shirt and it looks great with a belt and jeans. It’s also nice enough to wear with pants and pumps for work. I sized up to an 8 or 40 in European size in this top because I have broad shoulders. For a fitted look, you could size down.

Silk tops are a staple in a French woman’s closet and Sézane has amazing and beautiful silk tops in every season. This one above is currently sold out but I love this Chloé shirt, Léa blouse, and Ann top.

I took this linen dress, Winona to Paris this Summer and received so many compliments on the dress. It’s incredibly comfortable and such a beautiful-looking dress. It’s midi length with puff sleeves and a removable belt. The linen is not heavy and breaths very easily. This is one of those dresses I’ll have for years. I am wearing a size 6 in this dress or 38 in European sizing and it fits perfectly.

This is the Vic dress I wore all Summer long in a size 6 or 38 in European size. Sézane does basic dresses very well with the best detailing. I specifically love their midi-length dresses because they always hit me in the right spot and are very flattering when worn. This is a perfect size and I wouldn’t size up or down in this dress.

Sézane is known for its Will Jackets and this one in suede camel is beautiful and classic for Fall. I took a small in this jacket and it’s the perfect fit. The medium was too big which is surprising since I have broader shoulders. I am wearing this jacket with lots of jeans, sandals, and a lace or silk top underneath.

Sézane sweaters are my absolute favorite and one item I tend to buy multiples of in the Fall and Winter seasons. The sweaters are so incredibly made, soft, and timeless. Depending on the sweater I will either take my normal size or go up a size if I want it to be a bit roomier. For cardigans, I always take a small and for other fitted sweaters, I will go up to a medium.

A few of my favorite sweaters which are classic Sézane are the Gaspard Jumper, the Scarlett Jumper, and Achille Jumper.

I believe that you get what you pay for, and that includes shoes. I don’t mind investing in shoes now that I can wear them all day long and are going to continue to be comfortable for hours. I’ve had several pairs of Sézane shoes and boots over the years and they are absolutely worth the money.

The Jack Sneaker are probably some of the most comfortable sneakers I have ever worn. I took these to Paris and walked about 25,000 plus steps a day. Not once did I get a blister or any kind of rub from these sneakers.

They are beautiful leather sneakers that I took my regular size of 6.5. These sneakers are more of a cream vs. true white but you will not regret purchasing these sneakers.

Belts are one of those accessories I don’t think people think enough about. A belt can make an outfit come to life so easily. A beautiful one wore higher on the waist with a dress or around the waist with denim and a blazer. Think of a belt as the finishing touch to your outfit.

I wear a size 80 in the belts regardless if I am wearing higher up on my waist or with jeans. Two of my favorite belts are the Jones and the Artemis.

If you are looking to invest in high-quality and beautiful pieces that will last for years to come then Sézane needs to be on your list of places to shop.

As I invest and collect more pieces from Sézane I will continue to share about sizing as I know it always helps others. Please also leave a comment if you’ve ordered a piece and what your thoughts are on size.

  1. I really liked your run down of the sizing and the pictures of the items and the fit. Do you mention anywhere on your blog your measurements? I’m trying to figure out what will work with me with the Sezane items and I’m a little bit between a 6 and 8. I’ve taken my measurements, converted them to cm and compared to the Sezane size chart (thanks for the hyperlink!), but I’m curious to know how I would compare size-wize to you as an example. Thanks for this post. It was fun and lovely to read. (also the button below to submit comments looks invisible on my browser…)

    1. Hi Roxanne! I don’t think I mention my measurements anywhere. I am 5 5 1/2 and a small in tops and 6 in bottoms. I am an hourglass shape if that helps at all! Thank you for the comment button, I will get that fixed asap. Thanks for reading!

      1. Noey, thank you. I have been searching Sezane’s site for a size chart. I too wear small tops unless they button up. Because of my chest size 36D, they button shirts in small tend to pull and gap at the top buttons. Do you have this problem with Sezane’s button up shirts or do you always size up on them (I think I read you sized up on the button you posted a picture of). THANK YOU AGAIN for this great post!!!

        1. Hi! Yes, I know exactly what you’re describing. It depends on the top but most of their tops I will size up unless the top specifically states that it’s oversized, then I will stay with my normal size. I just ordered a few new button tops for Spring so will report back on the sizing of those tops. So glad the post helped! I would say size up and see if you’re comfortable. The best thing is they offer free returns so if it doesn’t work out you can always return the item.
