Plato's Closet Opinions ?

Well Im 13 and my aunt is taking me to the outlet stores in L.A. on June 13th. I am really excited because they have cute clothes but i only have $85. I want more than that when i go there so i am thinking about taking my old clothes that i dont wear anymore to plato's closet and selling them. i have never been there before but i have been seeing a lot of commercials for that store lately. also my friend said they are a good store. What are some opinions about Plato's Closet ?? Should I sell them old clothes ??
