X-CHENGFleece Lined Tights Sheer Women - Fake Translucent Warm Pantyhose Leggings Sheer Thick Tights for Winter

I had some exact looking ones like these & they wouldn’t stay up so I threw them away! Anyone have this same problem? I want to buy these if they stay

Are the feet lined in fleece?

The size chart shows rhe medium and large are the same. Is this accurate?

Did anyone else have to wait like three weeks to receive these?? Every time I checked the shipping status it says not shipped and they extend it .
