My cousin is getting married next month (April 27th) and I'm in the wedding, so I've obviously got my dress set there, but I'm struggling with the rehearsal dinner. The invitation said "cocktail attire" so I have a fairly simple, pale blue, chiffon shift-type dress, with a high neckline. I've attempted to attach the link (I'm new here). The color is listed as "Chambray Blue." I've also got some silver shoes, with a small heel and an ankle strap. I live in South Carolina, so I'm expecting the weather to be pretty warm by then but I am struggling to find something lightweight to go over this dress. I've looked at shrugs, wraps, boleros, everything, but so far nothing has seemed right. Any recommendations, as far as colors, prints, styles?
