Fashion brands are catching on to the social media craze and using tools such as smartphone applications to engage customers in a way that wasn't possible in the past. In addition to apps that cater to online flash sales, technology has made it possible to keep up with the latest trends, see what the celebrities are wearing and build personalized virtual closets. Mobile apps are changing the way that the fashion industry works in more ways than one.
The San Francisco clothing company Gap Inc. was one of the first brands to take advantage of social media to reach consumers. The Gap StyleMixer is a social shopping app for smartphones that allows people to mix and match Gap clothes with other items and to share the looks via social networking sites. In addition, the application also offers exclusive coupons and special offers.
While the Gap application was at one point innovative and new, it's definitely not on my list of favorite fashion apps. Here I've compiled a list of my most frequently accessed (and college-friendly-free) fashion applications for the iPhone:

Style.com
This app feeds the latest trends by connecting you to blogs, runway coverage, reviews and more. It's ideal during fashion week!

WhoWhatWear
This collection of celebrity-inspired styles in blog and collage form.

I'm sure most of you are familiar with Lucky Magazine. This phone app brings you the same clothes, accessories and beauty products as well as helps you track down where to buy them.
If you don't mind paying for an app, I would also recommend Stylebook ($3.99) which is similar to the Gap StyleMixer (free), and a great tool for organizing your wardrobe. Also, don't forget about the RueLaLa and Guilt Group applications for flash deals!
