......Uniform Adjustable Tailor Waist Liner (Fits up to waist 44")

The Premier tailor rubber waist liner is designed to be worn over the shirt tails and inside the slacks.  It helps the shirt resist pulling up while also helping to keep the slacks from sagging down.  Wear it for one week and then leave it at home and you'll suddenly be aware of how often you re-tuck your shirt in or hitch up your slacks.
