According to the GQ Guide for Shirting, your dress shirt should be a solid color with a straight collar and long sleeves. Patterns, button-downs and short sleeves are just too informal. Wearing a tie adds professionalism, select diagonal “rep” stripes, solids or a tiny pattern. Pants and jacket? Never wrinkled, always clean — that’s our job, and we’re happy to help. Take some time and polish your best shoes, choose dark solid color socks and fill your mind with positive, optimistic thoughts. Good luck!
