[header] How to behave like a contemporary gentleman [title] Pay attention to how you dress. [step] You don't have to dress " preppy " but you should make sure your pants, shirts and shoes are of good quality and in good repair. Gentlemen don't wear things that are scuffed, stained, ripped, ill-fitting, or otherwise in bad shape. 
Wear only clothes in which you feel confident. But don't try to be something you're not, women can always tell when you're faking it.
