Rayon silk velvet fabric is a plush, supple and invitingly luxurious blended fabric with an excellent drape. Lighter in weight than many other velvets, rayon silk velvet fabric has a loose and full-flowing style that is sensual and inherently well-suited for formalwear, dresses, capes and wraps. Rayon silk velvet can be hand washed in cold water, but dry cleaning is recommended.
