TOM FORD EYEWEAR Rosco aviator-style acetate sunglasses

If there's a brand to trust with aviator-style sunglasses, it's TOM FORD - the designer himself wears them often. This 'Rosco' pair is made from translucent gray acetate and fitted with photochromic UV-protective lenses - they change in the sun, shifting from light-brown to dark once you're outside.
