Is it good for feng shui for children to wear other people's old clothes?

Not so good. This has little to do with feng shui. Like other people's meals. Let you eat it again. Will you eat? Let's put it another way. Each has his own heart. Uncomfortable, and so is the child. Others wear clothes. Let the child wear it again. Are you sick? Children are obsessed with cleanliness. Is there a big taboo? Clothes are not expensive now. Why wear other people's clothes?
