The Scenario: The fact that your ex and his family are going to be at your friend’s wedding means one thing: You need to look fantastic. Unfortunately, your dress is too short, and you spent more time making sure your upper thighs didn’t stick to the pew than chatting up his mom.

The Recommendation: Next time, wear a nude-colored dress and keep the cut in the space between work wear and night-out garb. When your ex spots you from across the room, he'll regret that you two ever parted ways.
