This periwinkle silk Marc Jacobs dress would be really nice to wear to some summer weddings! It's got a slip, a ruched part in front, a ribbon waist-tie, and a lot of other nice details, and it's a REALLY pretty color. It's too big and a little too long for me, but maybe it will work for you? Hope so!
