Club Monaco's slim-fit 'Sutton' trousers look just like your classic houndstooth wool pair, but are a much wiser choice for warm weather. Woven with a smaller puppytooth pattern, they're made from naturally slubbed linen that's really lightweight and breathable. Try yours with loafers and no-show socks. Shown here with Club Monaco shirt, A.P.C. jacket, Common Projects sneakers.
