Size S, and the belt is also included. After being dry-cleaned on the "delicate clothes" course, it has been stored in a dark place with the cover on. It has only been worn a few times and is in beautiful condition with no major stains. I have dogs and cats, so although it has been cleaned, please be aware of this if you have allergies. I can add more photos if you'd like to see a specific part of the item, so please feel free to comment.
