Vintage fully Fashioned Stockings [ with seams ] should be rolled right down to the toe before putting on. They should be rolled on gently and eased over the heel. They should then be rolled slowly up the leg and the seam should be checked for straightness as this is done. Stockings should always be put on while the wearer is seated and with the legs lightly bent. The suspender should be fastened while the knee is bent and never too tightly, nor more than half-way down the welt. The side suspender should be at the side, and if the position of the suspender on the garment to which it appears to fall too far behind the line of the hip, it should be moved slightly forward, for the sake of the life of the stocking.
[ and I love this bit ]
Never smoke while putting on nylon stockings, as the minute particles of hot tobacco ash will melt through the nylon yarn and holes and ladders are bound to result. This accounts for many customers’ complaints that their stockings have given way, despite the fact that they had never been snagged or damaged in wear.
