Sage Green Skirt with built in shorts underneath

🕊Sage Green Skirt with built in shorts 🕊The tag says medium but I think it would fit a XS - I bought this skirt in a market in South Korea so this would probably be a Asian Medium which is much smaller than an US Medium 🕊There are built in shorts in the skirt that stops the skirt from riding up 🕊 Last 2 photos have measurements 🕊YesStyle like material - I originally bought this skirt in South Korea
