This is a cardigan in a very beautiful color. I think it's closest to the color "indigo blue." It's 100% polyester, so it doesn't wrinkle, and it's a perfect cardigan to keep in your bag for air conditioning対策 (cooling measures). I've worn it a few times, but I don't see any noticeable damage. Instant purchase is OK. Thank you very much. m(_ _)m Length...Mid Color...Blue, Green Sleeve Length...Long Sleeve Season...Spring, Summer, Autumn
