It's a really cool website, people post outfits and people can hype them. I really recommend getting an account if you have any interest in clothing, etc.
I have yet to post any looks, but I will post one in the coming week. You can follow me if you want; lookbook.nu/mattmyhomey
You guys should try www.looklet.com it's awesome.
You can create looks, upload it to Facebook, let people critic... more like a virtual runway.
