Many non-country folk think that wearing a plaid flannel is just part of the country concert "look." Although that is true in part, a flannel is more than just a fashion statement.
Once the sun goes down, things can get a little chilly, even if you are up and dancing around. Any good country girl knows that a plaid flannel is the perfect jacket to slip on when the air gets a little brisk. They're warm, but lightweight, and it doesn't hurt that they also look adorable!
