This is an ivory, spaghetti strapped a-line with slight flare at bottom dress.
I would have a ball with it (if it fit me) making myself this into a fantastic Halloween costume - trashy nightclub singer, zombie, whatever - its solid - zips nicely and all but has a few small holes and a few light spots....but that's why you could fix it up - a solid blank slate.

So here's the sizing: It fits a size 6 woman generously. It's 17" across bust (measured flat) and 56" long. Waist is about 14" across measured flat, too.
Its photographed with a slip under it that's not included....have fun with it - at this price, why not?
