Zara sizing — detailed breakdown

Zara uses European sizing with a fitted, tailored cut. The brand is notorious for inconsistency between collections, but the consistent takeaway from shoppers is to size up by one. This is especially true for:

  • Dresses and blazers — often cut narrow in the shoulder and waist
  • Jeans — Zara denim runs small and rigid; size up and expect to break them in
  • Knitwear — can shrink after washing; size up for longevity
  • Men's shirts — slim European cut; broad-shouldered men often need 2 sizes up

H&M sizing — detailed breakdown

H&M is more reliable for true-to-size shopping, though it's worth noting some variation:

  • Basics (t-shirts, jersey) — very true to size, good for online ordering
  • Divided / trend pieces — can run slightly small or large depending on collection
  • Denim — H&M jeans are more generous than Zara; true to size or size down
  • Formalwear — fitted blazers run true; check measurements vs Zara
