It's the skirt. Size is L. I wore it outside once for a short time. It's a complete set. I'll check, but I might have lost one of the buckles on the waist belt. However, it was very easy to come off from the start. It fit well even without the belt. The gloves, hat, and belt are adjustable. Personally, the skirt was tight around my thighs, but I was able to wear it properly. In the end, I wore pants, so I only tried on the skirt. I didn't use the belt and skirt on the day, and changed to black pants, so those who are interested in the skirt might like that too.
