Article: Starting with the bottom of the shirt, roll or fold the bottom of the shirt up until your torso is exposed. This gets the majority of the shirt bunched together in one place, leaving the harder parts, like the neck and arms, for last. Keep rolling it upwards, bunching it so that the bottom of the shirt is now around your shoulders. You may have to push hard to stretch the bottom of the shirt around your shoulders, depending on how tight the shirt is. Once the shirt is completely over your shoulders, pull the neckline up over your head. The folded lower portion of the shirt will still be stretched around your shoulders, and the sleeves will still be on your arms. If you need to protect your hair-do, use both hands to stretch the neckline over your head without touching your hair. Now that your neck is through and the shirt is stretched around your upper body, raise your hands up. The shirt will pop off of your head and you'll only be wearing the shirt on your arms. Simply lower your arms and remove the shirt. This might be a little tricky if the shirt has tight, long sleeves, but tug on the shirt until it comes off. You're now shirtless!

What is a summary?
Roll the shirt up your torso. Push the rolled torso portion over your shoulders. Pull the neck over your head. Extend your arms. Take the shirt off your arms.
