This is a long-sleeved cut-and-sew top from "GAULTIER JEAN'S," the second line of Jean Paul GAULTIER. The size is indicated as 40. I have listed it as a size S on Mercari. Please comment if you would like to know the detailed measurements. Also, the frequency of use is zero or only once, but to prevent any trouble, I have listed it as "Like New." If you have any other questions, please feel free to ask. Thank you very much! :)
