The problem is it's in cartel packs with stuff we DO want. I hate having a pile of bloody worthless skimpy stuff I can't even vendor (because sure as hell no one is buying it).
Then buy what you do
want from the GTN rather than the CM. That's what I do. I have yet to acquire a single piece of skimpy clothing I did not intend to buy.
Your cast-off junk will sell if you price it cheaply enough. All my characters' female companions wear hats like the revelers cap because those hats are so cheap (and I'm going to disable head gear display no matter what it is, so one orange hat/helmet is as good as another).
