UK Brands That Run Large

These brands are known for generous cuts, relaxed tailoring, or vanity sizing—meaning you may want to size down in many cases:

1. Boden

  • Designed for a comfortable fit, often with extra room in the waist and bust

  • Regular and petite options also run generously

2. Seasalt Cornwall

  • Known for loose-fitting cuts, especially in dresses and tunics

  • Best to check measurements carefully for knits and smocks

3. M&S (Marks & Spencer)

  • Good for fuller busts and relaxed fits

  • The Autograph and Per Una lines often run larger than other labels

4. White Stuff

  • Often oversized in style with extra room in the shoulders and bust

  • Size down for a more tailored look

5. Joules

  • Casual, roomy fits—especially in tops, fleeces, and coats

6. Phase Eight

  • Formalwear and dresses tend to have extra ease built in

  • Ideal for curvier body shapes, but may require sizing down


🇺🇸 USA Brands That Run Large

These American brands are known for generous US sizing, often catering to comfort and inclusivity:

1. J.Crew

  • Tops and dresses tend to run large, particularly in knitwear

  • Size down for more structure, especially in their relaxed ranges

2. Madewell

  • Their jeans fit true to size, but many tops, jackets and tees run loose or oversized

  • Extended sizing means some pieces run roomier than expected

3. Everlane

  • Boxy fits across tees, outerwear, and sweaters

  • Known for “relaxed” styling that often means sizing down for a neater silhouette

4. Old Navy

  • Designed with stretch and ease for everyday wear

  • Activewear and denim in particular run large

5. Universal Standard

  • Offers sizes 4XS to 4XL with intentionally generous tailoring

  • Great for curve-friendly styles but some garments feel oversized on smaller frames
