Wear contemporary pop's most-watched young face on the Billie Eilish Long Sleeve T-Shirt: Smile (Back & Sleeve Print) — officially licensed Billie Eilish merchandise via Rockoff, the genuine article for fans who treat Billie as a generation-defining voice.

The Smile design carries Billie's contrast between the sweet and the unsettling — the kind of dual-energy that runs through her catalogue from Ocean Eyes to Birds of a Feather. Treated as both back and sleeve print, the artwork carries from multiple angles.

Soft-style cotton in a relaxed unisex fit, long sleeves, classic crew neck. Pairs naturally with oversized denim, joggers, anything else with proper Gen-Z casual energy.
