Vintage Bill Blass one-piece suit dress size 6/8

Pristine condition authentic vintage Bill Blass suit dress in a size 6 or 8, (there’s no internal tags, except for the Bill Blass tag). Received this from a guy who collected couture gowns in a size 6 or 8 & kept them stored really well for most of the time. I’ve only worn this to work 1 day. The material is slightly textured with velvet accents, shoulder pads, fully lined, 3 hook-n-eye’s above back long zipper, & slight on back of skirt for easy mobility. Terrific item!!!
