It seems unfair that the only thing you can test-drive before you take it home is a car. (And, no, leaving the tags on a piece of clothing and returning it later does not count.)Now you can try before you buy when you rent a dress from stylist Nicole Lieberman of NBL Styling.Lieberman offers elegant frocks (Alice + Olivia’s brown sequin minidress, a red drapey number from Badgley Mischka, the sparkly Jimmy Choo V-neck frock shown here) for three-day rentals, with fees starting at $75. After you order online, the dress will be delivered, with a complimentary styling session with Lieberman or one of her associates, and then picked up when you’re done.She’s also got bags and shoes at the ready. If you simply can’t part with the dress, you can buy it at 20 percent off the retail price (minus the rental fee). It might just test your willpower.For more information, call 415-613-8657 or go to nblstyling.com.Photos: Courtesy of NBL StylingThe perfect accessory? A long, flowing mane.
