This is because it is important that you are dressed in a presentable manner. Men who are dressed well look more attractive and the chances of a second date also increases. Moreover, do not over dress. You are going on a date and not on a formal gathering. It will also make your personality look a bit too formal that will deduct points on your attractiveness. It is important that you dress according to the venue.
Dressing well is important because it reflects a lot about your personality. It lets the woman know how your social skills are what taste do you have. Your dress is the mirror of your personality. Therefore, make sure that you dress according to your personality.
Contrast is the key. Women like it when a man has a good sense on what colors go well together. Wearing all white is not such a good option. Play with colors but select something that has a touch of elegance and class.
Your clothing should bring out your masculinity and makes you more attractive and irresistible in the eyes of the women.
Keep in mind that as soon as you will appear in front of her, she will start making mental notes about your personality and would have already decided whether she wants a second date with you or not. Even before you have said a proper greeting.
