When the daughter is engaged, the mother should wear decent clothes, not formal dresses. It is more appropriate to wear red or brownish red clothes when engaged, because dignity and propriety can let the in-laws see from the clothes that the family's literacy must be very high. Try to wear loose clothes and wide-leg pants, even dresses, but don't wear tight clothes, because tight clothes are not suitable for talking to younger generations.
So is the son's engagement. You'd better dress dignified and generous. No matter whether your hair is curly or loose, you should comb it. In addition, it is best to wear loose clothes, not too gorgeous, just normal casual clothes, and the color can be darker, which makes people more calm.
Although the children are engaged, we can still see the most basic literacy and quality of this family from the parents' clothes, and the most taboo is not to comb their hair and then wear old clothes, which will make the other family feel very shabby. It is very likely that the children will bid farewell to this relationship before they enter the marriage hall. We must pay attention.
