They all, within one or two washes, start to creep up my bum. I have lost weight and have less bum to hold them...as it were, and I swear you used to be able to get knickers with nice firm elastic around the leg holes that properly hold them in place and don't sag after a couple of washes? I don't care so much about VPL, I am more interested in my arse not eating my pants.
