Having lunch with your ex-boyfriend? You need this Yellow Stripe Patchwork Chiffon Tank Dress ($31). It'll make you look hot, so he'll be fully aware of what he's missing out on. But it's also demure enough to make it seem like you weren't trying to be hot, so that he doesn't get it in his thick head that you were trying to impress him. Oh, and it also helps that it's only $31 - you've wasted enough of your precious resources on the jerk already.
