NEED TO SELL WEDDING DRESS/ BECAME PREGNANT

I bought a dress at davids bridal and found out I was pregnant and now I cannot wear it and it is brand new never been worn and davids bridal will not let me return it. It is style# 9E8787 on www.davidsbridal.com and is very pretty but I can not wear it and am needing to sell it. It is size 16W and I would say fits like a size 18 regular. I loved this dress and I hope someone else will love it. We payed $400 for it and will take best offer. Email me at sdazjenkins4@yahoo.com
