EXCLUSIVE AT MR PORTER. London-based brand Cutler and Gross has been making eyewear since the late '60s, so the esteemed brand is a natural choice to design specs for Kingsman. Made from acetate and silver-tone metal that feels really light, this early 1900s-inspired optical pair has round frames that'll suit most face shapes. Keep them pristine by slipping yours into the accompanying case between wears.
