Royal blue prom/formal dress

I am going to miss parting with this dress- i only wore it once to prom but it made me feel like I was on a red carpet!! I have no use for it anymore and would love to see it make someone else feel that beautiful. It is a gorgeous straight bodice with blue beading, thick straps (good support on top) and a slit (only obvious when pointed out). Zips in the back. True size 6 & originally $600. Willing to negotiate
