Joseph Sizing Guide: Does Joseph Run Big or Small?

Joseph runs true to size but with a distinctively slim, tailored European silhouette. This London-based brand is renowned for minimalist luxury pieces, but the French/European sizing system and refined cuts can be tricky if you're used to UK high street fits. Here's everything you need to know about getting your perfect Joseph size.

Understanding Joseph's Sizing System

⚠️ Joseph uses French/European sizing (38, 40, 42) NOT UK sizing (10, 12, 14)

💡 Pro Tip: French sizing hasn't been affected by vanity sizing like UK high street brands. What was a size 40 twenty years ago is still a size 40 now – this is why Joseph sizing feels smaller than brands like M&S or H&M.

How Different Joseph Items Fit

Trousers (Coleman, Den & Other Styles)

⚠️ Trousers run tight across the hips – most people need to size up

• Designed with precise seams and elongating fits

• Luxurious fabrics but slim through the hip and thigh

• If you're between sizes or prefer room, definitely go up one size

"Their trousers are gorgeous but tight across the hips—go one size up."

Silk Shirts & Blouses

• Can fit perfectly in the arms but run tight in the bust

• Tailored cut through the shoulders

• If you're fuller-busted, consider sizing up

"Silk shirt fit perfectly in the arms but tight in the bust."

Knitwear (Cashmere, Merino, Cotton)

• More forgiving than tailored pieces

• Elevated simplicity with refined finishing

• Check the length and hemline to avoid boxy fits

• Generally roomier and more comfortable

Coats & Outerwear

• Heavy and exceptionally high quality

• Run narrow in the sleeves

• Structured, tailored silhouette

• Consider sizing up if you layer underneath

"Coats are heavy and high quality but run narrow in the sleeves."

Dresses

• Clean lines with minimal detailing

• Fitted styles are particularly slim

• More structured than high street equivalents

Real Customer Feedback

"I'm a UK 10 and their size 38 was too fitted for me—needed 40."

"Their trousers are gorgeous but tight across the hips—go one size up."

"Silk shirt fit perfectly in the arms but tight in the bust."

"Coats are heavy and high quality but run narrow in the sleeves."

Who Should Size Up?

Consider going up one size if you:

• Have broader shoulders

• Are curvier through the hips and thighs

• Prefer a looser, more relaxed fit

• Are fuller-busted

• Are between sizes

• Plan to layer underneath (especially coats)

Men's vs Women's Sizing

Joseph menswear is slightly more generous than the women's line, but still leans toward slim-modern tailoring.

• Men's pieces maintain the refined, tailored aesthetic

• Still European sizing system

• Broad-shouldered men may still need to size up

• Consider sizing up for a looser fit

What Makes Joseph Sizing Different?

French Sizing Standards

Joseph adheres to French sizing regulations which are more standardised and haven't changed significantly over the years. UK high street brands have gradually increased their size measurements (vanity sizing), making a "size 12" today larger than it was 20 years ago. Joseph hasn't done this.

• Clean lines and contemporary edge

• Designed to skim the body, not hang loose

Quality & Construction

• Exceptional tailoring and finishing

• Premium fabrics: silk, cashmere, merino, Italian wool

• Precise seaming and structured cuts

• Timeless pieces built to last

The Bottom Line

Joseph runs true to European size but fits slimmer than UK high street brands. If you're used to M&S, Next, or other generous UK sizing, expect to need one size larger in Joseph.

Your Action Plan:

1. Know your measurements – bust, waist, hips in cm

2. Check Joseph's size charts for each specific item

3. When in doubt, size up – especially for trousers and fitted pieces

4. Order two sizes if shopping online and unsure

5. Try in-store if possible to get your baseline Joseph size

💡 Once you know your Joseph size, it's consistent across the brand – making future purchases much easier!
