A teddy, also called a camiknicker, is a garment which covers a female's torso and crotch in the one garment.
It is a similar style of garment to a one-piece swimsuit or bodysuit, but is typically looser and more sheer.
The garment is put on by stepping into the leg holes and pulling the garment up to cover the torso. It may cover the whole of the torso or partially and may also cover the arms.
They may open at the crotch for visits to the toilet, without the need to remove all clothing.
As an undergarment, it combines the functions of a camisole and panties, and may be preferred to avoid a visible panty line.
