Ever since 1913 when the T-shirt was first included as standard-issue gear in the U.S. Navy, the short-sleeved crew neck has become an essential part of the American wardrobe. Not long after the Navy, the Army followed suit, paving the way for the T-shirt to become the go-to top for dockworkers, farmers, miners and other workers who appreciated the comfortable lightweight cotton and short sleeves. By the 1920s “T-shirt” became an official American-English word in the Merriam-Webster dictionary.

In the 100 years of its history, the T-shirt has grown up from a workwear staple to one of the most flexible garments known to mankind, an article of simple clothing that can be found in just about any clothing store for anywhere from a few dollars to a few hundred. Or a few thousand? Indeed, last year French fashion house Hermès debuted a crocodile T-shirt with the not-so-humble price tag of $91,500, illustrating just how far the T-shirt has come.

In celebration of the beloved classic's centennial, here are some of the more memorable moments that mark its 100 years. Happy birthday, T-shirt!
