That is a cute ensemble, love the color and sparkliness. Her body type looks alot like my own, and well, I don't model for my auctions. Honestly, it would probably sell better on a hanger. (Did I just say that?)
Sounds like you have gotten into a deal that is going to end up being nothing but a pain in the rear. Been there, done that, won't do it again. You are a seasoned seller, if folks want you to sell items for them it needs to be done on YOUR terms, otherwise they can have a go at it themselves.
