Gorgeous floor length formal dress

F length dress perfect for a prom, military ball, etc. Halter neckline with large blue and black beads. Zips in the back. Mesh in the middle area is see through and there's a slit in the dress. Size 7, but the material is stretchy, so it can fit a little smaller or bigger. I typically wear a size 4 and it was perfect for me. Worn once for only 4 hours. In great condition. No stains or tears.
