Dog dress

I have 2 of these dresses I bought 1 for my dog (miniature dashaund) and it fits her but she is too long for it (it looks funny on her when she standing, when she sits down it looks ok, lol) the other one I bought for a friend and she didn't buy it off of me so I'm stuck with 2 I can't use. They are brand new. Im asking 20$ each or best offer. Size medium it has snaps at the bottom ???? have a great day!!????
