Isabel Marant Étoile Size Guide: What Size Am I in Marant Étoile? UK Fit Advice & Sizing Help

Isabel Marant Étoile — the younger, more relaxed diffusion line from the Parisian designer — has become a staple for effortless French dressing. Known for its casual-cool tailoring, slouchy silhouettes, and bohemian details, the Étoile line is more accessible than mainline Isabel Marant but still retains many of the same sizing quirks.

If you’ve ever wondered:

“Does Isabel Marant Étoile run big or small?”
“What’s my UK size in Marant Étoile jeans or jackets?”
“How does it compare to other European brands?”

You're not alone. At Tellar.co.uk, we analyse Marant Étoile’s full size structure and garment data — and compare it across 1,500+ brands — to give you a precise recommendation based on your actual measurements.

Does Isabel Marant Étoile Run Big or Small?

In general, Isabel Marant Étoile runs small across the board, particularly in trousers, jeans, and fitted shirts. Outerwear and knitwear tend to have a more relaxed cut but can still feel narrow in the shoulders or arms.

Here’s how it typically fits by category:

Category	Fit Summary
Trousers & Jeans	Run small with little stretch – size up one full size if unsure
Shirts & Blouses	Tailored through the shoulders – size up for broader builds
Dresses	Varies – looser in shape but fitted at the bust – size up if curvy
Knitwear & Tees	True to size or slightly loose – less of a concern than other categories
Jackets & Coats	Relaxed in body but narrow in sleeve/shoulder – size up for layering

Isabel Marant Étoile pieces are known for their refined proportions — they aren’t intentionally oversized like Ganni or Stine Goya, but they aren’t particularly generous either. Sizing up is common, especially for UK customers.

Isabel Marant Étoile UK Conversion Chart

Marant Étoile (FR)	UK Size	US Size	Bust (cm)	Waist (cm)	Hips (cm)
34	6	2	80	62	86
36	8	4	84	66	90
38	10	6	88	70	94
40	12	8	92	74	98
42	14	10	96	78	102
44	16	12	100	82	106

The brand uses French sizing (FR), which can be confusing. If you’re a UK 10, you’ll usually wear an FR 40 in Marant Étoile — but in many cases, FR 42 will provide a better fit due to the slim European cut.

To avoid guessing, just enter your measurements once at Tellar.co.uk — and we’ll instantly recommend your correct Marant Étoile size, based on bust, waist and hip data from actual garments.

How to Measure Yourself for a Perfect Fit

To find your true Isabel Marant Étoile size, use a soft tape measure and follow these steps:

Bust: Measure around the fullest part of your chest, under the arms
Waist: Wrap around the narrowest part of your torso
Hips: Measure the widest point of your bum, keeping the tape level

Then input your results at Tellar.co.uk. We’ll match your body shape not just to Marant Étoile — but to 1,500+ fashion brands, with no guesswork.

If you don’t have a tape, we’ll post you one for free when you create your profile.

What Real Customers Say About the Fit

From aggregated reviews on Net-A-Porter, Matches, MyTheresa, and Marant’s own store:

“Love the styling, but definitely size up in trousers.”
“I’m a UK 10 and usually buy a 40, but needed a 42 in the jacket.”
“Knitwear fits beautifully — true to size and not itchy.”
