The Tomboy is a popover silhouette with an easy, slouchy vibe, thanks to a deeper placket and a more relaxed body. (The buttons stop halfway down the shirt, so you can literally, yes, pop it over your head.) This one's made up in a pencil-drawn floral print from Liberty Fabric that was inspired by a subtropical meadow in Abbey Garden on Tresco, one of the islands off the Cornish coast.
