Thank you for viewing! This is a 20th-anniversary item from Jiyuku. It's a simple and sophisticated black V-neck long-sleeved set, size 44 (see photos 7 and 10). Made of 100% wool, but it's a washable material for comfortable wear. Both the top and bottom are made of a thin, glossy, felt-like material. The sleeves of the top are made of a knit material similar to merino wool. I purchased this and have kept it in my closet, unworn. Please refrain from purchasing if you are concerned. m(_ _)m
