Vintage studded 1980s jumpsuit one piece with shoulder pads size 12

J B wright Ltd awesome blue stonewashed jumpsuit with shoulder pads and studs. It is a size 12. I would say fits a modern 10 or so. I am wearing it in the last photo and I am a large or a 12. It is a smidge tight. Pit to pit is 20, waist is 14 across unstretched.
