Summarize the following:
Avoid leaving them buttoned since it will make your rolled sleeves too tight. Make sure you get all of the buttons, including any that are higher up along the forearm. Bring your other cuff up to the same point on your arm as you did on the first sleeve. Look in a mirror, check that your sleeves’ lengths match, and make sure the rolls don’t look too thick.  Additionally, make sure the same amount of cuff is poking out on each side. Sometimes called the Italian Roll, this style looks especially great when the cuff’s inside lining is a different color than the rest of the shirt. The contrasting colors can create a striking accent and add interest to your outfit.

Summary:
Unfasten each button on your sleeve cuff. Repeat the process to roll your other shirt sleeve.
