I've decided to sell these because the size didn't fit. I've used them about 4-5 times. I'm 175cm tall, weigh 75kg, and have a muscular build, but the M size felt a bit tight in the shoulders. If you're under 170cm and have a slender build, it should fit perfectly. 【Product Overview (from the HP)】 ★ ① Top - Cloud Pile Long Tee ★ ■ Fabric Carefully knitted with fluffy pile yarn in a high gauge, achieving a melting-like texture.
