As an added convenience for diabetic athletes who cary their insulin pump in the SHORTS, an insulin pump hole can be installed right below the waistband (in the skirt) and can be to the left or the right of the zippered pocket in the waistband. SparkleSkirts sewing staff considers the zippered pocket side to be the "front" and the non-zippered side to be the "back". Please choose the "right side" or "left side" based on this information. Once skirts are altered with music holes your skirt is considered non-returnable to SparkleSkirts for a refund! The charge is $3.00 for each insulin pump hole.
