How do you sell clothing on Wizard101

Sell clothing? You can't even trade cloths on wizard101! We can only trade treasure cards. I don't think we can sell them though. Sorry :( I know what you can do if you want to not have some of your cloths any more go to your castle or dorm room and click on your chest and move it to there or the attic that's what I did with this pet I won that I did not like I put her or him there(:
