I love mine, too - lovely cosy velour from M&S a few years ago, after they finally started making them long enough - I really hate those draughty mid-calf things - and I’m not all that tall at 5 foot 7.
More than once I’d previously asked M&S why they didn’t make longer versions - of course the answer was Health and Safety.
I bought it after buying an identical one as a Christmas present for a friend of the same height - she absolutely loved it, so after a while I wondered why on earth I hadn’t treated myself to one, too.
Static caravan purchase is it worth buying
