I'm ready to go big this spring with the puff sleeve--but not too big, lest I want to impersonate an NFL linebacker! This voluminous silhouette feels fresh and edgy after all the bell sleeves of late, and the airiness reflects spring's overall amped-up, oversize movement. I'd like to make a huge statement in these pieces by Rejina Pyo (above), Anna October, Mango, Ulla Johnson, Rosie Assoulin, Frame, Tibi and J.Crew.
