Jumpsuits started in the 1970s with the classic disco jumpsuit (bright colors, flared pants, etc). The jumpsuit changed a little bit in the 80s — instead of long flowing pants, the legs of the jumpsuits were tapered to give a more fitted look (like in the picture above). Both styles of jumpsuits are coming back, but the 1980s style is doing it a little faster and better.
These are actual sewing patterns from the 1980s for jumpsuits.
Jumpsuits can also give off a sophisticated vibe if styled the right way. Look for a solid colored jumpsuit and pair with heeled sandals or pumps to make the look more professional.
