I am sick of buying knickers that I'm having to keep hoiking up. I've tried M&S and Debenhams thinking the pricier pants would be better but the elastic is just crap and they're falling down as I'm walking about doing anything. I could almost live with that but I work in an operating theatre environment and can't be pulling pants up when I'm scrubbed. Please someone give me good and fair price knicker recommendations. No things though.
