Theory enlists French actor Alain-Fabien Delon as the star of its fall-winter 2016 campaign. This isn't Delon's first fashion outing. The 22-year-old actor also starred in Dior Homme advertisements. Continuing his foray into fashion, Delon connects with Theory for images lensed by photographer David Sims. Channeling an easy and confident attitude, Delon models the brand's fall essentials. The lineup includes a juxtaposition of slim-cut suiting and trendy standouts such as the fitted track jacket.
