When I first came to the U K and saw all the men in Dark suits I remember asking who had died. A good sales man would always mimic his clients or customers to make a connection with them and find common ground. Only a fool would wear a suit to sell to a windy as we will never wear a suit. Dress like us, speak like us and be like us and you will sell to us. Even when I convince I will take on the persona of my customers as I look for common ground to find there needs and wants. Read any sales and marketing book and you will see power dressing is not for the our industry. Some time these guys try to overwhelm you with B / S and intimidate you into buying.
