White tennis skirt NEW Women’s M/L

I bought this tennis skirt for my daughter, who normally wears a large, however, it was a bit small so I would say it runs more on the medium size. Please check measurements. It is new, never worn. Still has the clear tag attached but no brand. There are attached Lycra gym shorts underneath for modesty. Beautiful skirt. Measures: Waist across: 13.5” approx but does stretch. That’s unstretched measurement. Length: 12:5” approx
