If it's time for you to upgrade (or if you need an awesome holiday gift), check out these Chinchilla Collar Slippers. They are like furry little clouds for your feet--so cozy and comforting! A pair of these, a cup of hot tea and a good book and you are set for heaven. They feel awesome but they also look really good, they're quite elegant, so you still get your fur (faux) and warmth, but they look very feminine and would look great with that sort of sleepwear. Think cashmere robe (one can dream...). 
I also like Acorn's mules. These are a must have standard for three seasons and are great by the door for when you slip your shoes off and slide these right on effortlessly. Once you get used to wearing acorn slippers, you may not be able to live without them, you've been warmed.
