It's a good idea to have several half slips in varying lengths in your lingerie wardrobe. Plus size half slips come in lengths from a 14"" mini slip through 27"" slips, which fall below the knee, something for every outfit. When you're looking for some shaping and smoothing under close-fitting or clingy clothing, try a shapewear slip, which uses compression to create a slimmer, smooth silhouette. Under sheer clothing or skirts with a looser drape, plus size half slips with an a-line shape and gathered waist are comfortable for all-day wear. Slips with a slit that can be worn in the front, back or on the side are really versatile. Plus sizes in half slips go to 3X, which accommodates a waist of 36-37"" and hips of 51"" or more.
