I'm pretty sure Elvira Hancock would've worn this jumpsuit if she had her hands on it. The absolute best part about this disco creation is that is was reconstructed by a groovy dame who lived up in the hills of wealth but dedicated herself to volunteering at the zoo and other philanthropic activities. (This is why I love estate sales!)
It looks like it was originally a slip that she skillfully attached to some liquid silver pants. Top is sheer but back then, who cared?

Approximate modern size: XS/S (there is a little room for stretch in the bust and elastic waist)

Bust - 32-34 inches
