Sparkling Black Formal Dress

I have for sale a full length formal dress. It is strapless and it laces up in the back. There is 2 layers to this dress, the bottom is a silky solid black material and the top layer is a sheer material with sparkling flower designs on it. It is a size 7/8 by Niki Livas. I love this dress and there is absolutely no problems with it, but I finally managed to lose some weight and it does not fit me anymore. I do have a picture of it so if you would like to see it please email me at gibsonm@ksu.edu and I will send it out. I paid $100 for this dress but I don`t know where to start pricing it so make me an offer. Thanks!
