BA&SH (pronounced Bash) has become a go-to label for women who love effortless Parisian style. Combining relaxed silhouettes with bohemian flair and contemporary edge, BA&SH offers wearable fashion staples—from midi dresses to leather jackets—that feel luxurious but laid-back.

But with that French cool-girl aesthetic comes a question many UK and US shoppers ask:
Does BA&SH run big or small on clothes sizing?

In this guide, you’ll find out how BA&SH pieces fit across different categories, what size conversions to expect, and how Tellar.co.uk makes it easy to find your perfect size instantly—based on your actual body measurements.


The BA&SH Brand: Parisian Style with a Global Appeal

Founded by best friends Barbara Boccara and Sharon Krief, BA&SH blends polished femininity with relaxed, wearable cuts. Their collections are known for:

  • Soft tailoring

  • Boho dresses with ruffles or floral prints

  • Vegan leather pieces

  • Timeless blouses and trousers

  • Subtle sexiness paired with comfort

Although BA&SH operates globally, the sizing and fit are rooted in French design principles—which often means slimmer silhouettes and less built-in stretch than typical UK or US high street pieces.


How BA&SH Clothes Typically Fit

BA&SH uses French sizing, which can run smaller than UK and US equivalents—particularly across bust and hip areas. The brand also leans into relaxed shapes, meaning some pieces are intentionally roomy.

Fit Summary by Garment Category:

Garment Fit Observations
Dresses Run small at bust and ribs; relaxed at waist
Tops & Blouses Often true to size or slightly fitted
Skirts May feel tight at waist with zip closures
Knitwear True to size, with room to layer
Leather Jackets Slim in shoulders and sleeves; size up for broader builds
Trousers & Jeans Narrow through hip/thigh; check stretch fabric composition

“I loved the BA&SH wrap dress design, but the waist ran higher and tighter than expected in my usual UK 10. I went up one size and it fit like a glove.”

Does BA&SH Run Big or Small?

In short: BA&SH generally runs small—especially in structured dresses, trousers, and jackets.

Expect:

  • A closer fit across bust and hips in dresses

  • Shorter sleeve and torso length if you’re tall

  • Snug shoulder seams in coats and tailoring

  • No vanity sizing—BA&SH sizing is closer to authentic French/European proportions

BA&SH sizing assumes a lean silhouette with balanced proportions, so those with fuller curves, long torsos, or athletic builds may need to size up or tailor for comfort.


Fabric Types That Influence Fit

One reason sizing can feel inconsistent? BA&SH uses a range of fabrics—from drapey viscose to rigid cotton to structured vegan leather. Each material behaves differently:

Fabric Fit Characteristic
Viscose / Rayon Soft drape; may cling at bust or hips
Cotton poplin Structured, fitted at seams and bust
Recycled polyester Often lined; may feel restrictive in dresses or skirts
Vegan leather Stiff; typically runs small and structured
Merino / cashmere knits True to size with some natural stretch

Knowing what material the piece is made from helps predict how it will feel—especially if you’re between sizes.


BA&SH Size Conversion Chart (France to UK/US)

Since BA&SH uses French sizing, it’s essential to convert accurately—especially when shopping online from UK or US sites.

FR Size UK Size US Size Fit Notes
34 UK 6 US 2 Runs small—check shoulder/bust if fitted
36 UK 8 US 4 Most common BA&SH sample size; may feel snug
38 UK 10 US 6 Size up for comfort in dresses or waist-fitted tops
40 UK 12 US 8 Feels more true-to-size for UK shoppers
42 UK 14 US 10 Tailored styles still run lean at bust or hips
