Challis fabric is a lightweight, plain weave, soft to the touch, semi-fluid hand and often printed. It is usually made from rayon or wool but a new polyester version has been developed that is more sustainable, prints beautifully, and is more durable than its natural fiber counterpart rayon challis.

Due to the high popularity of challis, most fashion designers would use this fabric in making their clothing line. These ranges can be from loose-fitting tops to dresses, to skirts and even pants.
