I've always worn M&S high leg briefs, no issues. Time for replacement and I'm really unimpressed with the quality and cut of the same knickers. Off I go in search of replacement. I didn't think it would be such a task. Simple knickers that don't ride up my ass! Not a big ask. I've tried M&S flexi fit, high rise, low rise, Tesco, John Lewis, etc, sizing up, sizing down, briefs, shorts..... no avail. I just cannot find a pair of knickers that don't ride up my ass. Beginning to think it's my bum that's the problem. I'm looking for pants that cover my bum cheek (I don't like Brazilian cut) and don't ride up over the bum cheek. I do a lot of walking and they seem to shift and i spend half my walk discreetly fixing my pants!! Please help with your recommendations x
