I love wearing long sleeves and rolling it up until my elbow. Sometimes I have a hard time doing it that will look like it's neatly done.
Thankfully I saw this tutorial on How to roll sleeves like J Crew... I'm sure you also want to learn how to this way.
Step 1. Start with sleeves unrolled and unbuttoned
Step 2. Roll sleeve up to about two widths of the cuff
Step 3. Roll again to the bottom of the cuff
Step 4. Roll once more leaving the top of the cuff exposed
