Place a square of tissue directly behind the tear. Do this regardless of whether you're wearing the stockings or not.
Hold a can of hair spray 6 inches from the tear and spray it with a generous coat. Alternatively, coat the tear with clear nail polish, or if you don't have that, nail polish in a matching color. Run the nail polish brush up and down the length of the tear.
Moisten a cotton swab with nail polish remover and lightly dab it onto the nail polish or hair spray covered tear. This will remove the excess product so that your repair isn't as noticeable.
Adjust the tissue underneath the tear to ensure it's not sticking to the hairspray or nail polish as it dries. Allow the nail polish or hair spray to dry for three to five minutes and then remove the polish.
