We love a good 'Marmite' trend here at Who What Wear, and one of our favourite past-times is getting stuck-into a meaty fashion debate, even if it is via Slack. Well, we might only be 5 days into 2022, but the fashion sphere has already delivered a juicy winter accessory trend that has well and truly divided us editors. Love it or loathe it, knitted balaclavas are taking over this January.
