Rhia is a midi length kimono-style wrap dress with ruching at the bust, dramatic sleeves, and pockets. She is made of luxurious silk. Rhia is radiant. She's strong, sultry, and excellent at keeping secrets. She's an adventurer at heart. But...all high-quality silk is washable, even in a machine. The real question is whether or not you like silk after it is washed as the sheen on the material will dull over time. If you are ok with this evolution, then use the delicate cycle, and a delicate detergent, and wash away.
