Charmeuse

Charmeuse is a lightweight fabric woven with a satin weave, where the warp threads cross over three or more of the backing (weft) threads. The front side of the fabric has a satin finish—lustrous and reflective—whereas the back has a dull finish. It can be made of silk or a synthetic lookalike such as polyester. Silk charmeuse is more expensive and delicate but is softer and a better insulator. Polyester charmeuse is cheaper and can often withstand machine washing, but it does not breathe as well as silk. Charmeuse differs from plain satin in that charmeuse is softer and lighter in weight.
