I wear more skirts than pants due to easy fit and movement.  Vanity Fair produces very excellent quality slips at a reasonable price.  Due to the various lengths of my skirts and dresses, I have 6 or 7 half slips.  It is so easy to shop for slips on Amazon using their excellent vendors.  You "click" the size and color and place your order.  When shopping at stores, they may have your color, but not your size and or your size but not the color.  Stock using Amazon vendors is always quick and available for shipment.  I will  only purchase my slips on Amazon.
