Spacesuits

When jumpsuits jumped from utility to fashion, it was around the 70’s.
“The one-piece gained high visibility during the mid-1960s and 1970s when man took his first steps on the moon wearing a one-piece space suit and it was adopted by performers such as Elvis and worn by characters in movies such as Star Wars.”
