This a different way to cuff your shirt. A cool and yet very elegant way. And it goes like that:

- With an unbuttoned cuff fold the sleeve halfway up the arm, at your elbow height.
- Roll the bottom of the sleeve up the arm once or twice as you wish.
- Then smoothly pull the cuff..
- Scrunch the sleeve up as you wish.
- Tug the cuff once again.
- And voilà.
You can check via gif how to do this tutorial here. And bear in mind that you can leave more cuff showing if you want to. It is up to you.
Having options is always a good thing. And this could be that detail that would add some thing extra to your plain Jane look.
Give it a try. It is not hard at all.
