Old Navy White Skorts-Skirt Shorts

Very CUTE white skirt with attached shorts underneath. Double flap front buttoned skirt...fold over to the right to button once, then fold over the second flap to the left and button twice. NEW condition with tag but needs laundering as it has been collecting dust. Pet free and smoke free home. Sturdy All Cotton material. Not sure about the size. But it states SIZE 2. Looks like a size 4 to me but not sure. Check measurements. Measurement across the waist is 15 and 1/4”. Length is 13”
