Put on the shirt and smooth out any wrinkles
Button the shirt fully
Zip or fasten your pants or skirt
Tuck the shirt evenly into the waistband all the way around
Pull the shirt down gently so it sits flat
Make sure the side seams are straight
Adjust the front and back so there is no bunching
Use the military tuck if you want a slimmer fit
Fold excess fabric at the sides before tucking if needed
Sit, bend, and move to check that the shirt stays in place
Smooth the waistband area after tucking
Add a belt if appropriate to help hold the tuck in place
