is there anything wrong with being scruffy

As long as they are clean and you are clean, who cares?
And if they do care, why do they care?
I have a daughter who has done this her entire life, Or as I would think of it while she was in school, my little cartoon character.

I think it only matters if it's something more formal, like work. If theres a dress code or something.

I think the main thing is your joggers and hoodies need to be washed. There's "scruffy" as in not dressed up and there's "scruffy" when you're wearing sweat stained clothes that smell.
