Slim-fit pants or skinny jeans have a snug fit through the legs and end in a small leg opening. (This type of pants is known as "trousers" in the UK, to be distinguished from undergarments.) Other names for this style include carrot leg pants, cigarette pants, drainpipes, peg leg pants, pencil pants, skinny pants, slimjims, tapered pants, or ice-cream cone pants. Skinny jeans taper completely at the bottom of the leg, whereas drainpipe jeans are skinny but then the lower leg is straight instead of tapering and so they are often slightly baggier at the bottom of the leg than skinny jeans. In some styles, zippers are needed at the bottom of the leg to facilitate pulling them over the feet. Stretch denim , with anywhere from 2% to 4% spandex , may be used to allow jeans to have a super-slim fit. Skinny jeans are worn by men and women.
