EXCLUSIVE AT MR PORTER. The arrival of a new season calls for updating your wardrobe with key pieces, and that should include new glasses too. Exclusively made by Cutler and Gross for our in-house Kingsman line, this early 1900s-inspired optical pair is crafted from tortoiseshell acetate with round frames that'll complement most face shapes. The clear lenses can be easily switched out for your prescription or tinted UV-protective ones.
