A babydoll outfit is a two piece set which has a loose fitting top that is designed to end at or just below your bottom. The term babydoll is used because the nightware was designed to resemble that of a young girl's nightgown, although modern versions only vaguely follow this definition. Babydoll sets come in a wide variety of fabrics and styles. This type of lingerie is flattering to just about all body types. Women today should have several sets of sexy babydoll lingerie in their wardrobe.
