All rights reserved. Business wear is fairly standard, though northeastern cities like New York and Boston are a bit more conservative than places like Los Angeles. Both men and women in business wear suits, meaning the jacket is of the same material and matches the trousers or skirt. Shoes are well maintained and shined.
Women wear nylon stockings of appropriate color for the season.
Men wear neckties, and many women wear some kind of neatly tied scarf with a suit. Do Some Research. If you don't know how you should dress in a particular environment, do some research by observing how other people dress in that environment. Other than in fashion-oriented businesses, conservative American cuts for suits and jackets are appropriate. Since clothing and appearance means a lot in American business, be careful not to spend a lot of money on a high fashion item that doesn't work.
