Can anyone recommend really warm nightwear/ stuff to snuggle up in...that won't break the bank. I have a limited budget but I feel the cold so badly. Polyester is warm but seems to make me uncomfortable and sort of sweaty (even though I am not a person who normally sweats). I think a polyester dressing gown (if super warm) would be tolerable but not for anything next to my skin. I was looking at brushed cotton pjs but they seem pretty pricey! My feet are also an issue - always cold even with two pairs of socks on! Any suggestions? Thanks so much.
