I don't know if you read Into the Gloss -- it's one of my favorite beauty blogs, and I think you would like it -- but she recently spoke to Erin Wasson here for a feature called Top Shelf, which covers the hair and beauty routine of a variety of people (models, stylists, editors, etc). And Erin is SO Erin Wasson-y, you just have to read it.
I don't even know why I am putting this up to a vote. Get a room with that dress, hon.
