Dress Code
Where you conduct business in the USA will determine the appropriate attire. What is proper or not will depend on the climate and regional culture. Folks in the West are recognized for being a little bit more casual, whilst people in the East tend to dress more formally.
Until it is known what the acceptable dress code is, it is advised to always wear conservative clothing.
Men ought to dress in shirts, suits, and shoes. In most States, ties are worn, but not always. Traditional hues like black, blue, grey, etc. should be used.
Women should dress modestly and wear little jewelry and makeup. Tight attire, short skirts, and low-cut blouses are inappropriate. In many businesses, "Casual Friday" is the norm. Most employees at high-tech organizations dress casually every day.
