welcome Miss Chanel. To add a frag to your wardrobe, search for the frag in the directory. Once at the frag's page, on the left hand side, you'll see a drop down menu. Select "add to wardrobe" or any of the other options and presto, the frag will appear in your 'drobe.
As for reviews, as a non-supporter, they will not appear immediately. But on the frag's page, there is a box there for you to type your review, and a drop down menu to rate it.
