Eliza I don't laugh like a drain at all-in-one fleecy blankets suits anymore. When I was first married my father bought me a pair of zip up fluffy fleecy all in one pj's with feet in them which looked like and oversized baby-gro it did dampen the ardour of my new husband somewhat back then. I looked like a blue Elmo rather than a temptress but they were so snug and warm. The only worry I would have about fleecy blankets would be to trip over in it trying to answer the doorbell in a hurry. The benefit is not having to use much or any heating which is a great idea.
