Nancy Gonzalez

High-end retailer Neiman Marcus may have been slow to embrace social media, like many luxury brands, but in the last few months it's hosted a number of digital campaigns to boost its online presence. Now the retailer has almost 500,000 fans on Facebook and 50,000 followers on Twitter.

Neiman Marcus has launched its first-ever foursquare challenge to take place on Oct. 1. As part of the challenge, Neiman Marcus will hide 15 Nancy Gonzalez clutches in secret locations throughout its stores. Participants will engage in a hunt for the clutches by unlocking a message when they check into Neiman Marcus stores on foursquare.
