#17 - More Flannel Shirts - There is no question that a flannel shirt is the perfect autumnal attire. But you already own enough flannel shirts. You’re probably wearing one now. It’s a really nuanced plaid that your mom says looks great on you. And it does. But, you know what else? It looks good on the 40 other people in your immediate proximity who are wearing slight variations of that shirt. For the sake of crowds, and gatherings of any sort, let’s all just cool it on the plaid flannel shirts this fall. Go put on a nice sweater instead. Your mom thinks that looks great too.
