The Rosamund Blazer pairs a classic plaid with a bold contrast collar and zip pocket detail for a look that feels current without trying too hard. Made from a 98% polyester, 2% spandex self fabric with faux-leather and cotton contrast trim and a fully polyester lining, it's tailored through the body — the layer that pulls together jeans and a tee for a client meeting or tops off a slip dress for dinner after.
