Price Rollback Other Cosmobella/734509

This is an unaltered white wedding dress that I just purchased in November 2015. The original price of the dress was $845 but excluding taxes I got it on sale for just under $600. (Still have the receipt) Designer is Cosmobella. I ended up just having a small JOP wedding and never wore the dress. It laces up in the back so it's very slimming and the train is just the right length. It has some beading on the front & back and ruching in the middle part of the dress. It's a size 12. Very beautiful dress! Asking $400
