Uses

A tucked-in shirt look for the office or dressed-up days

This white long-sleeve poplin shirt is shown styled tucked into trousers, giving a clean, put-together look for dressier or office wear. In the styling, the tuck sits smooth at the waistband with a slight fabric blousing above the belt, so the standard fit drapes naturally rather than pulling tight.[1]
