We know first impressions are important, and we'd like to think they're primarily based on personality, right? Wrong. First impressions are largely about on how we look. So when you're getting ready for that all-important first date, think about what you are going to wear. Dress to impress, but also dress to show your personality. Keep in mind the activities you have planned for evening, and dress accordingly. If you initiated the date, make sure your invitee knows your plans as well so that he or she can dress appropriately.
