If your dress shirts are too long or too short, they will either bunch up around your waist or come untucked every time you raise your arms. Buying the right shirt length or having your shirts tailored to the proper length is the first step to keep dress shirts from untucking or billowing.
The perfect dress shirt length ends a few inches below the beltline. When trying on a dress shirt, make sure the hem covers your belt. Tuck in the dress shirt and raise your arms. If the shirt stays tucked in and doesn’t bunch up around your waist with excess fabric, you’ve found the perfect length.
