Is it wrong for a person who isn't a cowboy to wear jeans or a cowboy hat?
Is it wrong for a person who isn't a baseball player to wear a baseball cap?
Is it wrong for a person who doesn't play tennis to wear tennis shoes?
Is it wrong for a person who doesn't ride a bicycle to wear bicycle shorts?

There are no rules, make sure you mention that to the kilt police if you meet them
