In the world of men’s style, it’s often the smallest details that make the biggest impact. Collar stays are a perfect example. These flat, rigid inserts slide into the underside of a dress shirt collar to help keep it firm, aligned, and sharply pointed. Without them, collars tend to curl, flop, or lose structure—distracting from an otherwise polished outfit. Whether you're wearing a tie or leaving the top button open, they ensure a crisp, professional finish.
