Channel some old school cool this summer with Selima for J.Crew Rivington Sunglasses ($325). Handmade in France, these retro-styled shades feature a Rhodoid frame with plastic lenses in military-issue G-15 dark green, and are available in both black and tortoise. As an added bonus, they can also be fitted with prescription lenses for all you who've burned out your retinas staring at a computer screen all day — like us.
