Will anyone laugh at accepting relatives' old clothes?

No, everyone wears clothes given by others when they are young. Everyone can do it except the rich. When I was a child, I didn't want to pursue fashion or beauty, so I wore other people's clothes. When I was a child, all my friends around me wore other people's old clothes and felt nothing.

Maybe you just want to make up for your childhood wishes. You don't have to care so much about wearing other people's old clothes when you were a child. You can also ask your colleagues or friends, they certainly won't care.

There is nothing ridiculous about wearing other people's old clothes. If you don't like your children to accept other people's old clothes, it's not impossible as long as your financial conditions permit.
