"Người ta nói: Ăn cho mình, mặc cho người. Có lẽ nhiều phần đúng. Cô gái một mình trong hang sâu chắc không váy xòe, váy ngắn, không mắt xanh, môi dỏ, không tổ đỏ chót móng tay, móng chân. Anh thanh niên đi tát nước hay câu cá ngoài cách đồng vắng chắc không chảy đầu mượt bằng sáp thơm, áo sơ mi là phẳng tấp... Trang phục không có pháp luật nào can thiệp, nhưng có những quy tắc ngầm phải tuân thủ, đó là văn hóa xã hội. Đi đám cưới không thể loi thôi, lếch thếch, mặc nhọ nhem, chân tay lắm bùn. Đi đám tang không được mặc quần áo lòe loẹt, nói cười vang vang"
