Annie Georgia Greenberg, New York editor

The Peter Pan collar is a great way to accessorize and add flair with nary a lift of the finger. Annie's vintage Miu Miu dress has the party built in, but you can pair a more universal top with a flirty skirt that's already in your closet. Add a festive headband (or try a hair-wrapped milkmaid braid, as seen here!), and you're ready to rock!
