I have a brand new bridesmaid dress from David's Bridal for sale. It is style F12732 and the color is fern. I believe it is size 16, but I can let you know for sure if you are interested. It is a very pretty dress and very flattering. I paid $145 and I am asking $100 or best offer.
Here is a link to the dress:
