Slim-fit pants or skinny jeans (when made of denim) have a snug fit through the legs and end in a small leg opening that can be anywhere from 9" to 20" in circumference, depending on size. Other names for this style include drainpipes, stovepipes, tight pants, cigarette pants, skinny jeans, pencil pants, skinny pants, gas pipes, and skinnies. 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 come in a variety of colors and styles.
