I always bathed DD daily - it settled her at night and was part of the bed time routine. Clothes wise - she also had a set of onesies that were her "pj's" and I changed her each and every morning into proper clothes. The only time she ever wore onesies in the day was when she was ill.

I do recall having people tell me I was weird at the time and thought, as others have said, I don't like being in the same clothes all day and night so why should she?
