In March, I will attend the wedding of a good sister. What clothes should the bride's sister wear?

If you are the bridesmaid of the bride, if you want to be relatively formal, you can buy a little bridesmaid dress, which can be short and light in color, such as champagne pink, white, light blue, etc., or a dress that matches the color of your sister's wedding. Remember not to be dark or too bright, and the bride will think that you are strengthening her style. If you don't want to wear a formal bridesmaid's dress, you'd better wear a dress or a double skirt, and the color is also light. If you're not a bridesmaid, just attending her wedding, that's easy to say. All kinds of beautiful clothes will do.
