'By adding a white shirt you make dungarees urban rather than rustic, and grown-up rather than childlike'
I try not to pay too much attention, on the whole, to what is age appropriate or otherwise. (What's that? Oh, you'd noticed?) This is because, first, that way madness lies, and second (and most pertinently), if I open that can of worms I will end up talking myself out of a job. So, for practical purposes: la la la, I can't hear you.
