Traditional customs in China pay attention to red festivals and like to wear red dresses at weddings to show good luck.
In western wedding customs, white represents wealth and beauty. In its language, white is similar to light and sparkle. It is the sum of all spectra, the color of sunlight and the most perfect color.
If you must wear a white suit, it is recommended to wear a red tie (or bow tie), and red and yellow are often used in national celebrations in wedding scene settings.
