For me I prefer wearable layers, rather than blankets etc (they make me feel too sleepy and I hate then going into another room, I prefer my layers to come with me!!
I use thin layers, I need no assistance to look or feel like the Michelin man! Currently finding a long sleeve t shirt is enough mist if the time, but a shirt sleeve t shirt iver that and a cardigan if necessary.
feet - normal socks & a pair of ankle booties. Mine are from Wowcher £12.99 plus postage (they unfortunately have BJ on the side, but I forgive them for that. You can use them outside (designed as a snow boot) but they're light & soft enough for inside).
I live in leggings and have some thicker ones whuch I can pull over the top on icy mornings.
fleecy track pants would be cosy im sure, but they make me feel enormous, so I don't have any.
a woolly hat would help you.
I have a lovely soft scarf, I bought it years ago in a ski resort, just at a market, it wasn't expensive, but sadly I have no idea what it's made from (something man made I'm sure). It loop knots so it stays out & is gentle on my skin.
your nose might get cold, but does it really matter??
I couldn't wear fingerless gloves to knit, just knit something bigger that drapes over your hands.
ebrryones raving about electrical throws, check the electric usage before buying one, but most are very cheap to use & most people only need them turned on for short bursts.
