I didn't use these for my legs.  Thigh highs don't work well with flab....they just strangle your legs and make skirts and dresses look funny.  I purchased these to make the legs of a spider costume.  More often than not you receive the air filled plastic tubes in Amazon's packaging.  Used that to stuff into these thigh highs and then tied them off.  Voila!  I do have to say these thigh highs are durable.  All four pairs I purchased made it through a crazy Halloween night without a single run.
