SUMMER 27 Capsule Collection for COS

OPAL by COS offers refined, versatile pieces that transition seamlessly from the office to a night out without looking overly corporate or straight out of the club. Blending COS’ signature minimalist tailoring with subtle elements of cocktail attire that prioritize metallics, the OPAL collection is appropriate for any mature occasion.

OPAL reinforces COS’ existing brand identity of modern, timeless design and functionality, while functioning as an opportunity to appeal to younger female customers.

Designed for women whose workday doesn't end when the office does.

Brand History

H&M Group launched COS (Collection of Style) in March 2007 with the mission to create upscale, modern, and minimalist designs. COS opened its first store in London and later launched its online shopping site in 2011. The brand expanded outside Europe in 2014, opening the first North American store in Los Angeles, California.

COS bridges the gap between accessible pricing and high-end craftsmanship with core items ranging from $40 to $400. The brand’s identity is fueled by modern culture, innovation, sustainability, and timeless style.

COS’s main market is the United States, generating 24% of revenue in 2025. The brand’s e-commerce revenue in 2025 amounts to USD $846M (GMV), with an annual growth forecast of 5-10%.

Opal by COS expands the brand's footprint into contemporary women's evening wear, directly addressing the need for a special-occasion assortment.

Inspired by liquid metallics and nightlife, the collection delivers versatile, understated silhouettes designed to transition seamlessly from high-profile business events to late-night gatherings.

Opal honors COS’s commitment to minimalist design while introducing elevated, experimental textiles that drive incremental growth in the occasion category.
