Shopping Tips
COS uses dual sizing (EU and international). Their oversized styles are intentional — don't size down. For structured pieces like blazers and trousers, order your regular size. Knitwear may relax after a few wears.
Size Comparison
COS fits larger than Zara and H&M (its sister brand). Sizing is closer to & Other Stories. The relaxed aesthetic means pieces often work across adjacent sizes.
