COS Women's Size Guide
COS Women's Size Guide
Fit Summary
COS women’s tops follow minimalist architectural European cuts. Regular tailored styles run true to size; relaxed and signature oversized silhouettes have generous volume and often fit slightly large. Slim-fit pieces are neatly shaped and close-fitting. The brand uses EU sizing as base standard. Non-stretch woven shirts maintain structured lines, while cotton and fine knit styles carry gentle drape. Many shoppers size down for COS oversized tops for a less voluminous look.
Similar sizing reference: Scandinavian minimalist European sizing, more architectural and roomier than traditional sharp European luxury tailoring.
Note: UK / EU / AU / CN‑Size marked "≈" are approximate conversions for reference only. This guide covers women’s tops only; bottoms, dresses and outerwear are not included. Actual garment fit depends on fabric and silhouette.
