Why: It shows off your waist without looking too prim. How to: Tuck only the side that lays underneath the button panel inside your pants. J. Crew shirt, Citizens of Humanity jeans, $228, citizensofhumanity.com. Photo: Elizabeth Griffin.

Why: Business in the front, party in the back. How to: Tuck the front half of the shirt inside your pants or jeans, leaving the back half out. J. Crew shirt, $70, jcrew.com, Citizens of Humanity jeans, $228, citizensofhumanity.com. Photo: Elizabeth Griffin.

Why: It's less sloppy than a classic rolled sleeve. How to: Fold sleeve in half and pull to upper arm. Roll the fold up the arm again, stopping right below the sleeve cuff so it sticks out in the chicest way possible. Equipment shirt, $188, equipmentfr.com, Armani Exchange jeans.
