Shirt in or shirt out? We explain it all

For men, this is a recurring dilemma, but there are a few rules that make it easier to find your way around. First of all, let's start with the situations in which shirts should not be worn outside. When you're wearing a formal shirt, with musketeer cuffs for example, it's imperative that you tuck it into your trousers, as this helps to structure your outfit with clearly defined limits.

By definition, shirts are created for this purpose, as fabric is added to the bottom of the shirt so that it slips neatly into the trousers. For more casual shirts, the rule is more flexible and depends mainly on your personal taste, but it's important to take certain factors into account, such as your body type (if you're a little overweight, it's better to wear it tucked in) or the cut of your trousers. If they're high-waisted, a tucked-in shirt will elongate your silhouette, giving you well-defined legs while retaining the ease and casualness of a casual shirt. It's important to note that it's perfectly possible to wear it open over a t-shirt.
