step 1. pick a cute, fashionable outfit and wear it around a place that you know will be crowded.
step 2. take a photo and send it to a friend. pretend that it is just a casual picture of you in a party. he/she will realize how cute your outfit is(the plan) and gush all over you about it, and ask where you got it!
step 3. if they honestly love it, they will tell other people. if they asked you where you got it, it usually means, i'm interested in buying it too. people will ask them, and it will carry on! you'll feel like a true fashionista!
