One of the few beauty cupboard relics the luxury skincare industry hasn’t bothered to rebrand, just the word “flannel” conjures up images of rock hard soap on a rope, pungent Vosene bottles and mud coloured bathroom suites - complete with bidet. Flannels belong in a yesteryear world of dishcloths, peg bags and ornaments that require Brasso cleaner.

We now have the option of “professional cleansing cloths” made from muslin and coming in at 15 times the price of the good old flannel - but that’s not what our Kate’s all about.
