We designed this skirt with running specifically in mind. It's made with an extremely lightweight nylon/spandex blend fabric, and it has a cute scalloped edge that flatters most body types. It is made in the same sizable design as our cotton standard skirts, with the addition of an elastic band just above the "bum", with silicone inside the waistband to help keep it in place during runs. These features allow the fabric to 'cascade' over your derrière with a flirty, flattering look. You can wear the skirt over any length or type of running gear.
