Wearing the trousers is a commonly used phrase that implies dominance or control in a relationship or situation. However, several synonyms can replace this phrase without losing its intended meaning. Some of them include calling the shots, being in charge, having the upper hand, holding sway, or being in control. Each of these synonyms conveys the same sense of power, authority, or influence as the original phrase. These phrases can be used in different contexts, such as a business setting, a family dynamic or any other situation where one person has control, and the other takes a more submissive role.
