To wear this skirt, simply step into it and adjust the fold - over waistband to your comfort. It's perfect for 4th of July parties or any casual summer event. When it comes to maintenance, machine wash it in cold water on a gentle cycle. Avoid using bleach as it may fade the colors. Hang it to dry to keep its shape. As for sizing, it fits true to size, so you can order your regular size with confidence. Also, since it's not lined, it might be a bit see - through, so you may want to wear appropriate undergarments.
