Chinese wedding:
Mothers would better wear cheongsam or Tang suit in the Chinese wedding. And they will look extraordinarily vigorous when they are in fuchsia or pink. If mothers are rotund, they would better not wear cheongsam. But they can choose a cardigan or shawl to make them look slender if they want to wear it.
Western wedding:
If mothers attend a western wedding, they would better wear western dresses. The two-piece dresses or professional dresses are the best choices. And they can choose many colors while they buy a dress, such as black, purple and some other noble colors. The important attention they should pay is decent when they wear a dress. So they would better not choose a flowing dress which looks frivolous.
