Haruki Kiyama's brand, ASCENDED ・Long-sleeved T-shirt set (2 types) The white one is men's M size, and the brown one is men's XL size. Both are intended to be worn loosely, and although the sizes are listed this way, I believe they were originally one-size-fits-all. There is some wear, wrinkles, and fading. Please refrain from purchasing if you are sensitive to these issues. 【Instant purchase OK】
