I think static cling is also related to fabrication. . .I've wanted a taffeta slip to replace one that has gone missing for years, but they seem not to be made any more. I think I have also seen slips sold by Target, at least online and not the shapewear kind, either. I have held onto some slips for decades, despite their length being longer than what I wear currently, as well as a few owned by my late mom. Despite my full thighs, I don't get chub rub due to having bowed legs -- probably their only benefit! But I have a culotte style slip that would prevent that, but I bought it at least 30 years ago.
