This is a Familia undershirt. Size: 50cm * Although the size is listed as 50cm, I think it will also fit a 60cm size ^_^ New and unused, but since it has been stored at home... Please refrain from purchasing if you are sensitive to this. In the coming seasons, you can layer it with long sleeves, and in the summer it can be worn adorably on its own. Would anyone looking for this like to have it? Thank you for looking.
