Sport contemporary pop's most-watched young face with the Billie Eilish Long Sleeve T-Shirt: Smile (Back & Sleeve Print) in blue soft-style cotton — officially licensed Billie Eilish merchandise carrying the artwork across both back and sleeve.

The Smile design plays on Billie's signature contrast between the sweet and the unsettling, the dual-energy that's run through her catalogue from Ocean Eyes through Birds of a Feather. The back-and-sleeve layout runs the artwork at full venue scale.

Cut in a relaxed unisex fit with long sleeves and a classic crew neck. Available in a blue colourway. Pairs naturally with oversized denim, joggers and anything else with Gen-Z casual energy.
