If you were going to the office, you were most likely dressed in a full suit and tie.

Things began changing when the Hawaiian custom of Aloha Friday started to make its way across the Pacific, spreading east to California and winning over young working professionals who were tired of “dressing up” every single day of the week.

Like many holidays and social traditions, Aloha Friday was basically a marketing scheme.

It was invented by the Hawaiian Fashion Guild to sell more aloha clothing (i.e., Hawaiian shirts).

In short, a Hawaiian manufacturing association invented a novel custom of wearing casual clothing on Fridays, which paved the way for casual Fridays and business casual dress, in general.

Kinda random, huh?

The fact that it caught on so quickly and gained so much momentum, even though it started in the most remote American state – thousands of miles from most major U.S. cities – goes to show that men really just want to be comfortable, and most men aren’t very comfortable wearing a suit and tie.

Fast forward to the 1990s. Offices are more casual than ever, and many men are wearing jeans, shorts or even t-shirts to work. The idea of “casual Friday” has started to spread to the rest of the week.

The denim behemoth, Levi’s, notices a gap in the menswear market, and they decide to fill in the area between jeans and suits with their new line of khaki pants called Dockers.

They marketed these pants aggressively with hilariously “relatable” commercials like this one:

Even if Jerry hated these commercials, which at the time were very unique, they worked. Guys everywhere fell in love with relaxed fit cotton Dockers.
