What is a "boiled shirt"?

A boiled shirt is a type of dress shirt that features a heavily starched front panel, giving it a stiff and formal appearance. The starch used to stiffen the front panel is usually made from boiled cornstarch or rice, which gives the shirt its name. The rest of the shirt may be made from cotton or a blend of fabrics. Boiled shirts are often worn for formal occasions, such as weddings or black-tie events, and are typically paired with a suit or tuxedo. The stiff front panel helps the shirt maintain a crisp, clean look throughout the event, and can also help to highlight any accessories worn with the outfit, such as a tie or pocket square.
