I don't think I have a particularly saggy arse, but admittedly it's not what it was. I have struggled to find a pack of knickers which don't cut right in to my bum. The rise is too long on all the M & S ones, even the ones sold as low rise. I have tried the shorts, but they just felt like I was wearing a thong with no coverage on the bum. Im I being unreasonable wanting my backside to be actually covered by a pair of knickers?
Have tried primark too, same problem.
Have a pair from Rigby and Peller which are amazing, but cost about £20! The M & S ones used to be fine, but not any more .
