Starting with your pants unbuttoned, push the tail of the shirt down into your waistband. Make sure it’s straight and fully extended so there are no wrinkles. You want to start with as crisp and clean a foundation as possible.  The military tuck will work best with a shirt that reaches at least 3–4 inches (7.6–10.2 cm) below your waistband. Zipping your pants halfway up (but not buttoning them just yet) may help hold the shirt in place while you carry out the next few steps. Pinch the material between your thumb and forefinger just above your waistline. This will create a small dimple on either side of the fold. The place where you fingers meet will determine how much extra room you have in the shirt. Hold the fabric so that it sits close to your body, but not so snug that it pulls. Pull the material towards your back pockets so that it neatly overlaps the rest of the shirt. Try not to let the shirt tail crinkle or bunch up—the fold should lay perfectly flat in one piece.  It may be easier (and tidier) to pinch and fold the sides of your shirt one at a time so you can use both hands. The crease created by the fold will just barely be visible above your belt, and will be hidden altogether when you have your arms down at your sides. Finish zipping and buttoning your pants like normal. Then, cinch the belt down nice and snug to hold your carefully-arranged shirt tail in place. Use the palm of your hand to gently work out any wrinkles in the fabric around your waistline.   Avoid tugging at the shirt once it’s tucked. This is likely to just make imperfections worse. The military tuck is typically tight enough to keep a wayward shirt tail in place throughout the day.
