I used to wear hold ups, but with suspender belt (plastic fastenings).
I recently invested in a couple of nice 6 strap belts with metal fastenings, so decided to change to stockings as the hold ups were just ending up with holes in them.
The problem is though l, that even though the stockings say they are right for my size and height, they seem to end up just above my knee as if they are too short.
I use M&S in an XXL which says does up to size 24 (I'm 20-22) and I'm only 5'5 so no idea why they seem too short.
