I have a relation, who will remain unnamed, that turned her nose up at FREE, age appropriate clothing, for similar reasons.

As to freezing in the house, well, you must keep it pretty cool in there for that to be a possibility. I have just never been a fan of Jonah wandering around in his underwear....though, I do know people that think it is no big deal at all. I don't even like him in just his t-shirt and pants!
