Each day of the year always seem to be dedicated to something. Today, August 5th is dedicated as National Underwear Day. Why is it do we need a NUD? What is the purpose of the day? Well face it, you're probably wearing a pair right now. Aren't you? Boxers or briefs? That is the age old question. Grandma panties or undies?

According to the website-

In an effort to publicly shine light on “unmentionables,” Freshpair founded National Underwear Day on August 5th, 2003. Over the last 10 years we’ve celebrated the holiday with New York City model events, massive underwear giveaways, a pop-up shop in Columbus Circle, and a Times Square runway show.

In an unrelated story, it's also National Mustard Day.
