When shopping for premium denim and ready-to-wear apparel, few names hold as much influence as 7 For All Mankind. Often dubbed the “it” brand of designer jeans since its inception in Los Angeles in 2000, it’s a go-to for those seeking high-end, fashion-forward denim with luxurious fits and modern silhouettes.

But despite the quality and price point, many shoppers ask a surprisingly common question before purchasing:

Does 7 For All Mankind run big or small?

Let’s break down the facts.


Understanding Sizing: The Denim Dilemma

Denim sizing is notoriously inconsistent across brands — even within the same country. According to Tellar.co.uk’s comprehensive Brand Sizing Explained guide, sizing can vary by as much as two full sizes between labels. With designer denim, sizing tends to lean toward vanity metrics — meaning the label might say one thing, but your measurements say another.

In the case of 7 For All Mankind, their sizing approach aligns more closely with traditional American designer sizing, but with a few key nuances:

  • Women’s Jeans: Generally run true to size, but many wearers report that stretch styles can loosen with wear, especially in skinny fits.

  • Men’s Jeans: Typically run slightly large, particularly in the waist. Some shoppers recommend sizing down for a snug fit that won’t sag.

  • Tops and Outerwear: Tend to be true to size, but may run slightly narrow in the shoulders for structured blazers or jackets.


What Customers Say: Real Reviews on Fit

Thousands of reviews across Nordstrom, Selfridges, Harrods and other retail sites help paint a clearer picture:

  • Malia, size 28: “I ordered my usual size, and after a few wears the jeans felt too loose. I’d recommend sizing down if you’re in between sizes.”

  • George, size 32W: “These jeans fit large in the waist. I’m usually a 32 but needed a 31 for the perfect fit.”

  • Anna, size 26: “Very flattering and true to size, but they do stretch out a bit after wearing.”

These comments are consistent with Tellar.co.uk’s database of over 1,500 brands, which categorises 7 For All Mankind as a brand that leans slightly large in denim, particularly after wear.


Size Chart Discrepancies: Inches vs International

Another challenge for UK buyers is navigating American sizing charts. 7 For All Mankind’s size guide uses US numeric and waist measurements, which can confuse UK shoppers.

For example:

  • A US size 28 is approximately a UK size 10 — but depending on fabric stretch, it could feel closer to a UK 12 after a few wears.

  • Men’s jeans labeled 32W might fit like a 33W UK due to relaxed cuts.

💡 This is why Tellar.co.uk always recommends checking garment measurements against your actual body size in inches or cm rather than trusting size numbers alone.


Fit Types & Fabrics: Where Sizing Matters Most

7 For All Mankind offers a wide range of fits that can dramatically affect how true to size a product feels:

Fit Type

Size Tendency

Fabric Notes

Skinny/Ankle

Run small/tight

Stretch denim; may loosen after wear

Straight Leg

True to size

Some styles more rigid

Bootcut

Slightly large

Mid-rise, forgiving at the hips

High-Rise

Runs small

Best to go with true size or up if between

Boyfriend

Oversized cut

Designed to be roomy

Coated Denim

Runs snug

Tighter feel, non-stretch

Fabric composition also plays a critical role. Denim with 2–4% elastane will typically loosen over time, so users might benefit from sizing down for a snugger fit that adjusts to their shape.
