Poupette St Barth is the epitome of French island elegance — think floaty silhouettes, hand-printed florals, and carefree glamour. Whether you’re planning a holiday wardrobe or love their feminine resortwear year-round, one question arises quickly: what size should I get in Poupette St Barth?
If you’re unsure whether the brand runs small, how their French sizing compares to UK/US charts, or which pieces are worth the investment, this Tellar.co.uk size guide will walk you through it all — plus show you how to find your perfect fit instantly and for free.
Who Is Poupette St Barth?
Founded by a French designer nicknamed Poupette, the brand was born on the sun-soaked shores of St. Barthélemy. It blends bohemian energy with Parisian chic, making it a go-to for jet-setters, stylists, and modern romantics.
Expect to see:
-
Breezy mini and maxi dresses
-
Elasticated waist shorts and skorts
-
Lightweight embroidered tops
-
Floral jumpsuits with relaxed drape
But while the vibe is relaxed, getting the right size can be less straightforward — especially when French sizing meets international shopping carts.
Does Poupette St Barth Run Small or True to Size?
Most customers find that Poupette St Barth runs small, especially in the bust, hips, and waist for more tailored styles. Their French sizing tends to translate one size smaller than UK equivalents.
Here’s a quick size conversion chart:
| Poupette Size | UK Size | US Size | EU Size |
|---|---|---|---|
| XS (34) | UK 6 | US 2 | EU 34 |
| S (36) | UK 8 | US 4 | EU 36 |
| M (38) | UK 10 | US 6 | EU 38 |
| L (40) | UK 12 | US 8 | EU 40 |
| XL (42) | UK 14 | US 10 | EU 42 |
Tip: If you’re between sizes or curvier in the hips or chest, we recommend sizing up — or better yet, using Tellar.co.uk for a personalised fit based on your measurements.

What’s Worth Buying from Poupette St Barth?
From iconic mini dresses to versatile co-ords, these are the must-have pieces that offer the best fit and longevity:
1. Clara Mini Dress
The Clara is a bestselling, flared mini with flutter sleeves and an elasticated waist. It’s a flattering choice for petite and hourglass body types — but runs quite short. Size up if you’re tall or want extra room at the waist.
2. Jana Romper
A summer favourite, the Jana romper features wide legs and a cinched waist. Perfect for pear and athletic body shapes. Use Tellar.co.uk’s hips-first fit guide to get the exact waist-to-hip ratio match.
3. Bella Maxi Dress
Floaty and feminine, this piece works beautifully for fuller busts and apple shapes. Choose your size based on chest and torso length — longer torsos may need to size up to avoid pulling.
4. St Barth Skorts
Hybrid shorts with a skirt overlay — ideal for travel, beach clubs or everyday wear. The elasticated waist fits true-to-size for most, but check your hip measurements for the best drape.

Common Fit Questions (Answered)
Is Poupette St Barth good for petite women?
Yes — many of their dresses are short, floaty, and lightweight. If you’re 5’3″ or under, the mini dresses hit at the perfect length. Taller shoppers may prefer the maxi options or size up for added coverage.
Are the fabrics stretchy?
Most Poupette styles are non-stretch woven fabrics, but with clever design features like:
-
Smocked panels
-
Elastic waists
-
Adjustable ties
Still, this means getting your size right really matters — and Tellar’s measurement matching tool helps avoid the trial-and-error.
What if I’m between sizes?
Use your largest measurement (bust, waist or hips) as your sizing anchor. Tellar’s system does this automatically, recommending the right fit even when the sizing is inconsistent.
