- Elastic - Hook and Eye closure - Hand Wash Only - FUCTION - The closure has three rows of hooks so it's very sturdy, as is the elastic around the waist. The straps have nice metal clips to adjust the length and attach to stockings. The hooks kept the stockings in place day and night. - DESIGN - Retro style emphasizes your waist and looks very feminine. It's easily fastened and can be unhooked entirely to use the restroom if needed without unhooking the stocking straps. The straps are adjustable for slightly varying stocking lengths. -SIZE - Size chart is shown on the left image. Please find your size according to the extent of your waist.
