Wear it to the knee or slightly above the knee, neither too short nor too long, otherwise it will look sexy or grand, which will easily attract others' attention. 5 points or 7 points is the most appropriate, and the heel should be within 5cm, about 3cm. Try not to choose too bright colors and patterns. Pink, beige or light green can be used, and there is no need for cool colors, because it is a festive occasion, and red and purple are not good, because you are a bridesmaid. Simple elegance shows that you are elegant and fit your identity, and inheriting cheongsam also shows that you respect your friends. As long as you choose it properly, it will only add to the icing on the cake.
