Formal Bloomingdales dress in stores still

Just bought this dress a week ago at Bloomingdales for a wedding, still on racks. I wore it for 3 hours but now that my whole family has seen it, it's time to give it a new home! I loved it, :) also still have the tag it's just not attached I'll send it to you tho just to have, why not. I read online people seem to think this dress runs small which I don't agree with the xs was too big on me I had to pin it up in the back a lot, but Iv put the measurements up from the Bloomingdales website!
