If you're very thin (as pole dancers should be) you likely will have a hard time gripping the pole with your legs to do tricks, as the fabric will cause you to slip. The issues here are:  1. She should have no trouble gripping a pole with her massive fatty thighs  2. Why not wear shorts designed for this? You spent hundreds of dollars on those high stripper heels anyway  3. She can't actually do any tricks on the pole, don't need to grip if you do literally nothing.  Whenever hams "pole dance" they're the equivalent of acrobats who don't actually do any tricks
