The Jcp Teen store clothes are available now, but only a few are in the "New" section. You can find the rest by searching or go to this link founded by Underneath Stardoll. Click here to get all the clothes in your dressing room.
Some clothes are Nonsuperstar, and reasonably priced. These remind me of Kohl's. It is part of a campaign for go back to school so you will shop there :P
I also noticed in the new section there is a glitch. There are 2 of the same shirt but one is $8 & one is $7. Buy the cheaper one ;)
