Explain in English
A man who cares a lot about his clothes and appearance
As an adjective, dandy means excellent. If you think your new car is dandy, you're excited to own such a great car. In modern use, dandy is often used sarcastically, with just a small change in wording or emphasis: "My new car is just dandy. It's broken down twice today already!" The word dandy is also frequently used in the phrase "fine and dandy".
