This is a truly wonderful jacket, pants, and skirt suit! The outer fabric is 100% wool, and the lining is 100% cupro. I bought it because I might need a suit for work, but I no longer need it, so I'm selling it. If you need a refined, high-quality suit, please consider it! As the saying goes, "People are judged by their appearance," and wearing this suit will make you look 100 times better and improve your luck! The jacket and skirt are size 40, but they are a slim fit. The skirt has a slit in the back. Why not wear this and have a wonderful spring?
