The size is listed as 90, but it's a slim fit, so I think it's actually size 80. There are no noticeable stains. Worn only a few times. I will remove any pills as much as possible before packing. Navy cardigan featuring a pearl neckline and ribbon. Perfect as a cover-up for dresses, for celebrations, or everyday wear. - Color: Navy - Design: With ribbon - Embellishment: Pearl neckline - Back design: Simple - Made in Korea Thank you for looking.
