Side Button Sweater Buttons detail knit sweater Open Collar Button Up Sweater COMMENSE Toggle Shawl Collar Sweater Blue (S) Trussardi Touch of Modern. A textured buttoned up cardigan look thanks to the fixed toggles, but this piece is actually a very comfortable, very layerable pullover. We love the lightweight, fitted feel, and the texture especially on the shawl collar. Looks great layered over a work shirt or a plain white tee. The toggles add contrast that complement the visible texture. With a hem that sits at the hip.
