Have you heard about WikiFashion? It's basically Wikipedia for fashion and it's a total duh to make sure all your clients have their own profiles. Madeline of Lola PR came up with the concept and has been generously adding profiles herself, despite the fact that as a Wiki, it's basically open for anyone to edit. Check out PR Couture's WikiFashion page, if you're interested.
Recognizing an opportunity, Madeline is now opening up WikiFashion to partners like tech savvy fashion PR agencies to 1) become experts in the editing process and 2) be recommended on WikiFashion for profile development. Basically you'd be saying that for a fee, you are willing to work with brands and fashion personalities to get their pages up and keep them maintained. What a great way to get in front of new potential clients!
