We’ve all been there before: so and so’s glamorous, year-defining party is coming up next weekend, and our whole existence depends on finding the absolutely perfect dress for the occasion, but every damn thing we try on is either sooo last-season, or super kitschy, or makes us muffin top like Kirstie Alley in a Catwoman suit. It’s every girl’s worst nightmare.

Well, it WAS every girl’s worst nightmare. Not anymore.
