It’s a picture that has become a staple of online social networking. The self-portrait-in-a-mirror cell phone camera picture adorns Facebook and Myspace pages of young people almost everywhere.

Recognizing the opportunity that the ubiquitous “mirror shot” presented, Diesel Spain installed booths in their dressing room areas. The touchscreen boxes let shoppers take pictures of themselves in their Diesel clothes and post them on Facebook, getting instant feedback on their styles from Facebook friends. The picture includes a Diesel logo in the corner, so it’s clear where these clothes are from.

While most businesses are trying to figure out how to drive traffic to their Facebook pages, Diesel has taken another approach and brought Facebook into their store locations. Have you heard of another clever use of Facebook in a retail space?

Facebook isn’t the only place Diesel has engaged customers online. A one-day event at their flagship New York store offered special prints of tee-shirts to customers who checked into Foursquare within a three-block radius. The campaign netted 44 check-ins and 17 tweets. It was a low-key introduction to Foursquare’s capabilities for the brand, and eschewed some of the common tactics used, such as special badges or a longer duration.
