I have a high recommendation for Tyler-sized pantyhose by Dale Rae Designs. A one-person shop, this store manufactures its own high-quality hose and stockings for dolls: Tyler, Tiny Kitty, BJDs, American Models and more. The prices are very reasonable, and you'll be amazed at the fast delivery times. But more than anything--the quality is fantastic. The weave of the stockings is closer to scale, and they are easy to put on, and the fit is right on.
Two thumbs up for this store!
