The so-called “Ivy” style began with students at American East Coast colleges experimenting with sportier, dressed-down versions of gentlemanly British wardrobes. A perfect example is the unstructured suit jacket, which takes the sturdy fabrics and classic silhouettes of a British sports coat and makes it more casual with light construction and no shoulder pads. Kamakura Shirts’ version of this jacket is based on the preferred style of university students in the Fifties, coming in English gray herringbone wool tweed from Abraham Moon & Sons or a Japanese navy corduroy. Both can be dressed up with proper slacks and a necktie or dressed down with jeans. All of the details are pure Ivy: natural shoulders, a narrow three-inch lapel, a three-roll-two front closure, no front darts, a patch pocket on the chest, patch-and-flap side pockets, and a center hook vent at back.
