Marine Serre Size Guide: What Size Am I in Marine Serre? UK Fit Advice, Sizing Help & How to Get It Right First Time

With its iconic crescent moon prints, body-conscious silhouettes, and futuristic approach to fashion, Marine Serre has become one of the most distinctive luxury labels of the past decade. The Paris-based brand merges sustainability, sportswear and couture into every piece—but while the designs are progressive, the sizing isn’t always straightforward, especially for UK shoppers.

Whether you're shopping the signature second-skin tops, tailored outerwear, or hybrid leggings, this detailed size guide will help you understand how Marine Serre fits—and how to choose your correct size based on real UK body types.

For a faster, more accurate result, use Tellar.co.uk—we match your body measurements to over 1,500 brands (including Marine Serre), giving you personalised recommendations that are far more reliable than a generic size chart.

Does Marine Serre Run True to Size?

Not always. Marine Serre sizing can vary considerably across categories. Some items (especially mesh and jersey tops) are ultra-fitted, while other garments—like coats, outerwear, or denim hybrids—have a more structured, tailored shape.

Here’s what UK customers typically experience:

Mesh Tops / Second Skin Series: Very tight, body-hugging fit with lots of stretch. Most shoppers find these run small and size up for comfort.
Tailored Pieces: Jackets, trousers and structured tops tend to follow standard French sizing and can be narrow at the waist and shoulder.
Hybrid Sportswear: Leggings, catsuits and bodysuits often fit compressive and can be short in the torso if you’re tall.
Dresses: Fit varies between collections—many have a snug bust and a more forgiving hip, but always check the material and cut.

The fit is often more fashion-forward than forgiving. To avoid returns, Tellar.co.uk’s sizing tool gives instant answers based on your actual body, not your guess.

Marine Serre Size Conversion – UK to FR

Marine Serre uses French sizing. Here’s a rough comparison to UK sizes:

UK Size	FR Size (Marine Serre)	US Size
6	34	2
8	36	4
10	38	6
12	40	8
14	42	10
16	44	12

Keep in mind: stretch items (like crescent moon tops) may use XS–XL labels, while tailoring sticks with numeric French sizing.

Popular Marine Serre Items – Fit & Size Notes

1. Second Skin Moon Top (Mesh)

Super-fitted mesh top with thumbholes, signature crescent print and high neck.

UK Fit Advice: This runs very small—expect a tight, compressive fit. Size up if you’re in between or have broader shoulders.

2. Moire Denim Trousers

High-waisted, rigid denim with hybrid panels.

UK Fit Advice: Waistbands run tight, and hips have limited stretch. Many UK shoppers go up one size for comfort.

3. Catsuits / Unitards

Sporty one-pieces in stretch polyamide or jersey.

UK Fit Advice: Suited to petite or athletic builds. Taller customers may find the torso short—check your rise and shoulder-to-hip length.

4. Regenerated Fleece Jackets

Oversized fleece with hybrid layers.

UK Fit Advice: These tend to run large—your regular UK size will give you an oversized fit. Size down for something more tailored.

How to Measure Yourself for Marine Serre

If you're investing in designer clothing with tight tailoring or technical fabrics, you need more than just your UK dress size. For Marine Serre especially, the safest approach is to use your real measurements:

Bust: Around the fullest part of your chest
Waist: At the narrowest point of your torso
Hips: Around the widest part of your lower body (including bum)

Once you've measured, you can enter your details at Tellar.co.uk for instant recommendations—no calculators, no guesswork.

Tellar will also send you a free measuring tape so you can get started properly if you don’t already have one.

“The mesh top looked amazing but I had to size up. It’s super fitted, almost like shapewear.”
— Leila, London

“I’m usually a UK 10 and went for the 38 in the denim trousers. They fit, but I wouldn’t go tighter. The waist is high and rigid.”
— Natalie, Glasgow
