A teddy, also called body and camiknicker, is a form of bodysuit-like lingerie, often worn in the boudoir. It is an undergarment which combines a camisole and panty in one piece. Unlike a bodysuit, it is typically looser and sheerer, and may be designed to slip off from the shoulders, rather than to open at the crotch.
A babydoll is a short, sometimes sleeveless, loose fitting nightgown or negligee intended as nightwear for women. It sometimes has formed cups called a bralette for cleavage with an attached loose fitting skirt falling in length usually between the upper thigh and the belly button. The garment is often trimmed with lace, ruffles, appliques, marabou fur, bows and ribbons, optionally with spaghetti straps. Sometimes it is made of sheer or translucent fabric like nylon or chiffon or silk.
