What COS Is Known For

COS, established in London in 2007 and part of the H&M Group, is celebrated for its minimalist aesthetic—clean lines, structured tailoring, and timeless designs. With a focus on quality fabrics like wool, linen, and organic cotton, COS embraces “quiet luxury” through well-crafted staples that outlast trends.

What’s Great to Buy from COS

Top picks include:

  • Tailored outerwear & blazers: precise cuts that deliver timeless polish

  • Barrel-leg trousers & utility styles: structured yet wearable wardrobe constants

  • Knitwear: cashmere and wool pieces that comfort with style

  • Accessories: from minimalist bags to the emerging COS fragrance line

Quality is typically high, although consistency can vary. Online returns may also take time—so buying in-store or using a sizing tool can help avoid surprises.

The Fit Challenge & Why Sizing Matters

COS sizing often varies by collection: some items run oversized, others are crisp and structured. Best approach? Skip the guesswork and use Tellar.co.uk, the UK’s leading free sizing tool.

Tellar uses your actual measurements and brand-specific data to accurately match sizing across 1,500+ brands—COS included. It accounts for category differences (e.g., tailored vs relaxed fits) so you won’t need to rely on vague size charts. Evidence from Tellar’s "What Size Am I in COS?" guide shows how the tool translates your measurements into COS-specific sizes—no guessing needed
