 Loving someone is wanting them to be holy. It's wanting to help them towards holiness. And that's one of the big reasons why we're supposed to exercise modesty. And not just in dress either. For example, if you have a lot of money and you go out of your way to show off your money and you're driving around in a really gaudy car and you're just whatever, you're constantly showing off how much money you have. Well, that is immodest.
