This is a 3-piece set from PUMA, including a black polo shirt, pants, and socks, all in size M. I've worn them twice, but I'm selling them because I bought new ones. Please refrain from purchasing if you are concerned about the items being stored at home for a long time. They have been washed and stored. Polo shirt: M Pants: M Socks: 25cm - 27cm The size felt just right for me, I am 173cm tall and weigh 63kg, with an average build. The 3-piece set will be shipped via Yu-Packet Plus.
