The invitation reads “cocktail attire” but you’ve stared into your packed closet, muttering, “I have nothing to wear.” That sparkly plum dress is looking dated and your slinky little black number doesn’t feel special enough. By renting a dress from an online service or local boutique, you can get the latest looks for a fraction of the cost of buying.

These three dresses — all available for rent — highlight some of the hottest holiday trends: gold, back, patterns and long sleeves.

The dresses: Dresses range from long and sparkly to short and, well, sparkly. If you’re headed to Vegas or looking for a New Year’s Eve showstopper, this is your spot. Brands include BCBGMaxAzria, Adrianna Papell and French Connection.

The prices: Dresses retail for $500 to $1,500, but rent for $75 to $150 for a weekend. (Longer rental times are available.) An insurance fee of $5 is added to each dress to cover the cost of normal wear and tear. However, if you ruin the dress, you’ll be charged for its full price.
