3 Mori Lee Strappless Dresses (Lilac) 4 Sale

I ordered these dresses through a very reliable online source, except the maker (Mori Lee) makes these dresses a little small, so three of the dresses do not fit my bridesmaids. So, I am having to order 3 new dresses and would like to sell these. I can send a picture if you would like to see them. They are beautiful. They are strapless, two pieces, A line, and lilac. The are brand new, never been worn (haven`t even been tried on) and still in the bag. I have a size 4 and two size 10s. I paid $71.76 per dress. If no one needs them, does anyone know where I can sell them?? Please help.
