What I don't understand is why men have decided that they like wearing hats indoors. It makes no sense to me.
Sadly, I don't really believe in the idea of timeless fashion. It's an oxymoron. If 'classic fashion' really never changed, we'd all still be wearing togas.
No matter how fine your suit and your shoes, you will remind everyone that you are not yet a grownup man by wearing them with your old college knapsack, in its nasty, nylon glory.
