Site Lookout: LOOKBOOK.nu
lookbook.nu will definitely satisfy anyone's craze for current trends and streetwear. I'm actually going nuts over the pass few months looking at multiple leggings, skinnies, scarves, bowler caps, sunglasses, necklaces, blazers, trenchcoats, and vintage bags. It might not exactly be sartorialist-ish, but I'm sure if you're a designer, you'll be able to relate. Fashion is kinda our next best friend.
PLUS POINT: Tons of pretty girls in pretty outfits. :D
