Sometimes a square, an oblong, an oval, or a circle just won’t quite give your face the character—studious, kooky, glamourous, take your pick—eyewear is supposed to impart. If so, try something reminiscent of geometry class: the pentagon. Miu Miu’s five-sided frames in tortoise shell have a hint of the retro about them, but the gold-tone metal arms are decidedly today’s aviator. We’re also partial to the gradated blue lenses, a whisper of a contrast to the rather vocal frames.

Miu Miu’s appeal may be waning (if the closure of the Ion Orchard store is any indication), but their accessories still have powerful allure. Trend-defying, they have a certain goofiness that balances sophistication, and boldness that matches elegance. In other words, they’re cool.
