Definitely tacky to recycle, also to borrow is just odd.
I gues you could get away with it, but if I saw you in a formal dress you wore before I would know right away as well as any hair, make-up, jewelry, and physique changes. I just notice small things like that.
On tangential note: those of you that have no use for your formal dresses. Is it because you bought like prom gowns or you never go out to nice places that require you to dress up?
Get out more, live a little, its nice to get dressed up
