COBALT BLUE Now this is a sexy jumpsuit perfect for all the parties you’ll be attending. It’s the kind of outfit you should wear when you’re not entirely sure if the attire for the party is dressy or casual, because it can go both ways. Just wear a blazer over it during the day (or not, if you’re not going to work or anything) and then reveal its glory come night time! Look at that draping. Beautiful, right? Simple but striking–there’s a reason why it’ll always be my number one choice.
