This is a Petit Bateau size 6A. ＜6a＞→116cm (Suitable height 112-124cm) It gives the impression that it's slim and a bit small. It's reversible, and the arms are removable, so it can also be used as a vest, allowing it to be worn for a long time. Because of this, I wore it quite a bit. Please understand that it has been washed at home before purchasing! I think I bought it for around 17,000 yen.
