that may be also worn as a dress. Slips fall into two major categories. A full slip hangs from the shoulders by straps that extend down to the top of the breast area, with a skirt below the bust. Full slips come in a variety of lengths; some extend down to the upper thigh, some to just above the knees, or just below the knees, while others go down to just above the ankles. A waist slip, "half slip", or "underskirt", is held on to the body around the waist by means of an elastic waistband. The waist slip is also available in the same lengths as the aforementioned full slip. Waist slips that extend down to just above the ankle are often called formal slips, or
maxi slips.
Mini slips are yet another size option for waist slips. They were first introduced in the 1960s to wear under a mini skirt. American Maid manufactured waist slips that had vents and a rear
zipper in addition to the elastic waistband. These slips were made of half
nylon and half dacron
polyester. As an alternative to the full slip, a waist slip with a matching
camisole can be worn to provide full coverage. There is also similar garment designed to be worn under thin or light-colored slacks, called
trouserslips or
pettipants. In addition to pants, a
pettipant may also be worn under a dress or skirt, and like slips, they are mainly made of nylon or as a layer of luxury, in silk. == Decorations and fabric ==
