For mending pants with a fallen hem or shortening those that are too long, the top dog of fashion stylists is TopStick ($4.25 for 50 one-inch strips, Style Beauty & Barber Supply, 800-244-9352). Although it's technically toupee tape, Top-Stick doubles as a trouser saver: Insert a few strips into the cuffs and they do the job of a tailor without the wait. In theory, it's only a temporary fix, but these strips can withstand a few washings, rendering a needle and thread as unnecessary to you as a barber is to a bald man.
