See US Midwest M. Avoid wild patterns, flashy dresses, suits, and accessories. Be conservative in fragrance, makeup and hairstyle. Stay away from the low neckline, and the length of your skirts and dresses are best not the extremely long or extremely short look. Finally create a small kit of personal items and include it in your briefcase when going to job interviews.
