Stretched well without accidentally pushing my finger through. I rarely wear nylons. Being able to wriggle into them without erupting into obscenities is a huge compliment. It took me two wears to destroy them. Usually I barely make it out the door. If you buy these once a year because you are forced to get Foo Foo these are for you. They were the perfect level of sheerness. Not too thin, not heavy like tights. Only had to adjust and pull up twice and never had to pinch out a wedgie. Can't go wrong with these.
