Vintage 80s Aerobics Workout Bodysuit

In excellent vintage condition, some slight fading, but lining is pristine and seems seldom or even never worn. Vintage size 12 with low back and high cut legs. No material tag, the outter is cotton and the lining is some sort of spandex blend. This is not a swimsuit. listed as a size small, please see measurements. This will not fit a modern 12, more like a 6.
