I love the fluffies from TheSkyWasPink (link here), an Etsy seller based out of Denver CO. I got a pair of the aqua glittery ones in October - they're very soft and warm! I'm thinking of getting a rainbow pair (as seen above). If anything, they're fun costume pieces that can fit people of a variety of sizes (there's elastic at the top to keep them from falling down). They also come in a ton of colors - check them out!
