Thank you for viewing! This is an overall from Deuxieme Classe. I've worn it a few times, but it's in relatively good condition. The waist part has buttons and is removable. It can also be worn as denim pants. (I have never removed it and worn it that way) There was a tag that said 27, I'm not sure if that's the size. For reference, my usual size is 36, or a size M.
