I’m sorry, but you can’t just rock up to a casual lunch with your parents wearing a half open shirt, chest showing. In what realm is that acceptable?
If I went to lunch wearing the female equivalent of that, my father would march me out of the restaurant and put a coat over me. Mate, it’s midday at a family restaurant what the damn hell are you showing chest for?!
I don’t see why it’s an issue. It’s a casual lunch with his parents. Plus it is considered fashionable over there? And let’s be honest, there’s often a double standard when it comes to how the son is allowed to dress vs the daughter.
