Adjustable pouches may adjust with zippers, snaps, buckles, clips, rings, drawstrings, velcro, and other methods. They often have elastic in the waistband, drawstrings, and may or may not have pockets. In the mid-1990s bin bags with drawstrings for closure were introduced. They can be found at the end of cords and drawstrings. In either style, the drawstrings were decorated at length with pearls and jewels.
