Monsoon’s Brisbane sunglasses vs American Apparel vintage

I always feel like an idiot when I wear sunglasses, so this summer I’m on the hunt for some sunnies that have a little je ne sais quoi without making me look like a you know what.
Monsoon’s Brisbane sunglasses (£18) are pretty cool, I like the way they sublty allude to the ’80s without the full-on twattish moronic references. Mind you if you are going to wear sunnies you may as well go the whole hog and have some fun right? American Apparel’s retro shades are £30, pretty hot and now I’m feeling a little confused.
