If you like polka dots, this is the dress for you. A vintage shirtdress with cuffed three-quarter sleeves and a chic collar, the dots are broken up a bit by a striped pocket and collar. Fun, yes? While the original belt comes with the dress, you could always swap it out for a black one, or perhaps a winey-red one if you want real pizazz. The skirt is a full circle, so you'll get the ultimate in retro fullness and swoosh; the skirt also hides two more pockets.
This is a rare larger vintage dress, too: 46-38-full hips. It's an eBay auction that ends Saturday, with the bidding starting at $32. Good luck!
