Q. I have a daily problem with knickers. I am size eight so not obese, but I find the sort of tiny lacy thongs I am expected by my peers to wear to be really uncomfortable since they always ride up. What should I do?

A. The tyranny of thongs has already peaked so I am surprised you have not ‘cottoned on’ to the new craze for M&S pure cotton full briefs (£5 for a pack of five).
