We dare you to count the number of times you've shelled out fifty bucks for a cheap-looking number just because your wardrobe has decided that--nope, it has absolutely nothing to offer for you to wear to your friend's wedding / to Friday's date / to getting smashed at your office's holiday party. You still counting? Embarrassed? We thought so--but thanks to the ladies over at Rent the Runway , you can show up in Proenza instead of its last-minute, knockoff version. With over 35 designers in a full size run, Rent the Runway carries the entire contents of your fashion dreams, from flirty Yigal Azrouel frocks to classic Catherine Malandrino gowns. Simply reserve your dress on the date you need it, and your order will be quickly shipped to you along with one in another size to ensure the best fit. Wear, enjoy, then return the next day in a handy pre-paid envelope (the fit-kit that includes double-sided tape, a clip bra converter, deodorant wipes, and breathmints are yours to keep, you lucky things!). After trying it for ourselves (in a zip-backed Proenza Schouler so fierce it eats other dresses for breakfast), we have to agree that the whole system is tons easier than stressing yourself out at the nearest fast-fashion shop. So kick that buy-and-wear-once habit to the curb--and just for you Refinery29 readers, you all can beat the wait-list and sign up here now. Though, keep your hands off when the new Vena Cava comes in. We'll fight you for those pieces.
