The first date is sort of like a performance. You are presenting yourself to a stranger to see if they like you. With that said, you shouldn’t pretend to be someone else. Everyone likes someone who is real. However, if you really are a person who curses a lot, you might want to tone it down on the first date. Be sure to be at your best, smell good and dress nice. For women, showing a little bit of cleavage is fine. For men, wearing a nice dress shirt is a plus. On a first date, it’s important to be respectful. You can let your guard down on future dates, but there will never be another date if you mess the first one up.
