This is an Adidas skort purchased overseas. I wore it a few times in middle and high school, but I'm selling it now as I haven't had the opportunity to wear it since. There is no inner pocket for tennis balls. Please be aware that the elastic has loosened slightly due to age. There is some thread coming out from where the tag was cut, but there are no other noticeable stains. Size (measured by hand, so please use as a reference): Waist (flat): approx. 30.5cm Length (flat): Front approx. 26.0cm, Back approx. 30.0cm Thank you for your consideration.
