Young Brunette Girl On The Couch In Transparent Bodysuit

Azzedine Alaia and Donna Karan helped make the bodysuit a defining item of eighties fashion for both men and women. Onesies (or snapsuits) are bodysuits for younger children, toddlers and some adults which help keep diapers (or nappies) in place. The purpose of the opening at the crotch is to facilitate access to the wearer's diaper (or nappy).
There are also bodyshirts, like the counterpart to the bodysuit, they are loose-fitting garments that cover the whole torso, with sleeves in short to long lengths and crotch snaps. The difference is that they look like a shirt on the top portion of the garment, and may have a different stretch fabric in the waist to the crotch area to make them fit better.
