However, most fans were confused why the Princess had tucked such a thick jumper into her trousers made of lighter material.
Instagram user @goosegirlenfys said: “So cosy and festive. I wonder if the jumper ended up tucked in because it kept snagging on the branches.” Another fan, @austy_spumante added: “I tuck in my thinner jumpers into my trousers…sorry everyone.
“I love this outfit, personally. Looks very cosy and comfortable. I honestly wouldn’t have even thought twice about the tucking had I not read these comments.”
One fan saw the funny side of the debate, with @vcp214 saying: “Kate is causing some great debates. First the blue versus plum trouser suit in Boston and now tucked versus untucked jumpers.”
