Salvatore Ferragamo's Resort 2012 collection. Don't you love the way the blouse ties at the back? There is a definite infusion of 1930s elegance into this collection. You can purchase a few of the looks from the collection, including this one, through Moda Operandi.
For something keeping in the same retro style, and a bit more affordable, check out this, this and this on Etsy.
