I think everyone who considers themselves as gal should try to see as many street snaps as possible. Magazines are great, but advertisements aren't always 100% reliable in terms or realistic/accepted ensembles. To get my weekly fix, I go to Style Arena. This site has all the goodies I need in terms of street snaps. I love seeing them in my magazines, but the more the better.
*That link goes straight to the most recent snaps in Shibuya.
