BlackBook are the latest mainstream media outlet to acknowledge Tumblr's influence in the fashion industry. As a response they have curated their "Ultimate Fashion Tumblr Directory". While ultimate may be a little extreme (what happened to all the menswear focused sites?) this is a pretty good list for anyone just starting to feel out fashion's presence on the mico-blogging format of the moment. We'd also like to take a second and remind everyone that we are on Tumblr too!
