If you don’t want to spend a ton on a dress you’ll wear once, maybe twice, sign up (for free) at this clothing-rental site. Generally, renting a piece from a designer like Hervé Léger, Catherine Malandrino, or Tibi costs about 10 percent of the retail price, which means you can score a $1,590 cocktail dress for $150–and that includes shipping both ways and dry cleaning. (To ensure a perfect fit, you can pick two sizes.)
