Explanation:

Queen Victoria was the one who started the trend of white wedding dresses. In 1840, the queen married Prince Albert of Saxe. At the wedding, she wore a long white dress. At that time, women chose blue for their wedding dresses because it was a symbol of purity.

White was considered a symbol of wealth. At that time, wearing a long white dress was a sign that the bride was rich enough to buy a dress that she would never wear again (because white clothes were not easy to wash).

Because white was rarely chosen as a wedding dress, the queen's white dress surprised everyone. After that, white became a popular color in weddings throughout Europe and America.

Nowadays, brides can choose any color, but white still holds the number one position. From Europe and America, the tradition of wearing white wedding dresses has spread to Asian countries. Even in China, where red bridal dresses traditionally symbolized good luck, modern brides also choose white for their wedding day.
