The size is M. It's different from what I expected, so I'm selling it since I won't be wearing it. It has been opened once, but I only unfolded the clothes and haven't worn them. After opening, I put it back in the bag, so I haven't checked for any initial defects. The bag condition is not good since it has been opened once. Please refrain from purchasing if you are looking for perfection or are very sensitive to details, as it has been opened.
