Plaid was hot for awhile then it faded out of style. Seems like plaid pants are making a comeback so I am glad I still have a pair. Still have some plaid shorts too but have not worn them in a couple years.
I have plaid shorts and wear them occasionally. I also have a kilt that I save for really special occasions. I like it, it's fun, but I feel like you need a really plain shirt to pair with them.
