Can the blanket be fleece and never gets not super comfortable? Does it get dirty? What happens if it gets cut of or tethers apart? Do you die? Does another one grow back?

If you can take off one blanket but have to replace it with another one within like 10 seconds. That'd be fine. Could have like 5 or so blankets on stand by. Also you could get different fabrics for different outfits. Get a nice fancy one to wear with suits. Get a thin airy blanket for the summer, like a woven one with them holes in it. You could wear a towel when you bathe or swim. And whenever you're cold you could wrap it around you like a poncho.
