Why do Korean new daughters-in-law wear hanbok at home during their wedding?

Traditional Hanbok is very expensive, so you usually only get a high-end one when you get married. If conditions permit, make another set when the child is one year old, and then make a new set when he or she reaches his 60th birthday. Of course, if you are very rich, you can make Hanbok for some formal occasions or celebrations, but ordinary people will not make so many, and they don’t wear them often. Isn’t it a waste to make so many?

Wearing Hanbok after marriage is very particular, and you have to wear it until your mother-in-law asks you to change it. My mother-in-law doesn't tell me to change, so I have to keep wearing it! This should be a kind of wedding etiquette, but I don't know the specific situation very well.

I only know this, so I’ll take a seat first and wait for the master’s perfect answer!
