Envelope Dress by Isaac Mizrahi

That knock-'em-dead, stares of envy, how'd-she-do it dress that you must have for your upcoming class reunion is here at last. Check out this autumn gold Envelope Dress by Isaac Mizrahi ($50). The classic A-line shape is figure flattering, and we really like the discreet front pockets. But the best part is the back, which features a unique button closure, meaning you'll look stunning as you walk away from that jerk who stood you up for junior prom.
