Why does the groom wear a hat when he gets married? In fact, local customs are different. The groom should wear a hat when getting married, which is also one of the traditional etiquette. In the previous marriage, the bride was required to wear a hat, which is why the previous wedding is different from the present wedding, and this custom is still maintained in some places. But now in many places in China, grooms don't wear hats when they get married, so the custom of wearing hats comes from different places. Not every groom who gets married everywhere needs to wear a hat, but if it is a Tang suit wedding in China, it is necessary to wear a hat. If the groom wears a suit, half of them don't wear hats.
