One of our favorite online stops, Archive Vintage, just put their entire stock of retro fashion books on sale. A few of these classic tomes are going for as low as $25, and considering the quality here (Scavullo's Women, David Bailey, The Art of Being You by Gianni Versace, and Sonia Rykiel), they're definitely priced to go. So, if you're building your fashion library, this would definitely be a good place to stock up.
