What do you mean by reasonably priced? It's all relative.
At the beginning of March, figuring that I would be at home a lot more, I bought a pair of the most expensive slippers I've ever bought, the UGG Scuffettes in Leopard. They are so comfortable and stylish that they make me happy every time I put them on.
I also got a pair of cashmere blend lounge pants from Biba at House of Fraser with the matching hoody for a bargain price and I love them. They're very comfortable, warm but also I can throw a coat on and trainers and go outside in them too!
