Western Style Business Suits
The uniform impression of a suit can carry numerous connotations. In business settings, it can communicate respectability and taste. In different milieus, the connotations of corporate life that the suit represents convey unadventurous conformism. Extreme variations on the suit (like flamboyant colours) can convey the opposite.
Because wearing a suit conveys a respectable image, many people dress in suits during the job interview process. An interview suit is usually a conservative style, and often made of blue or grey fabric. Interview suits are frequently composed of wool or wool-blend fabric, with a solid or pin stripe pattern.The style of an interview suit, however, will depend on the organizational culture of the industry in which a person seeks employment.
Suit etiquette for men
Buttoning the suit jacket
The buttoning of the jacket is primarily determined by the button stance, a measure of how high the buttons are in relation to the natural waist. In some (now unusual) styles where the buttons are placed high, the tailor would have intended the suit to be buttoned differently from the more common lower stance. Nevertheless, some general guidelines are given here.
Double-breasted suit coats are almost always kept buttoned. When there is more than one to fasten (as in a traditional six-on-two arrangement), only the top one need be fastened; in some configurations, the wearer may elect to fasten only the bottom button, in order to present a longer line (a style popularised by the Prince George, Duke of Kent).
Single-breasted suit coats may be either fastened or unfastened. In two-button suits the bottom button is traditionally left unfastened except with certain unusual cuts of jacket. Legend has it that King Edward VII started the trend of leaving the bottom button of a suit undone.
When fastening a three-button suit, the middle button is fastened, and the top one sometimes, but the bottom is traditionally not designed to be (although in the past some jackets were cut so that it could be fastened without distorting the drape, this is not the case with current clothing). A four-button suit is untraditional and so has no traditional guidelines on buttoning, but the middle ones at least should be fastened. Additionally, the one button suit has regained some popularity (it is also a classic style for some Savile Row tailors). The button should always be fastened while standing.
With a single-breasted suit, it is proper to have the buttons unfastened while sitting down to avoid an ugly drape. A good double-breasted suit is usually able to be left buttoned, to avoid the difficulty of constantly redoing inner buttons when standing up.
Ties with suits
Working with neckties is very much a matter of personal taste, but in conservative terms there are some basic guidelines.
Colour: Ties should always be darker than the wearer's shirt. The background colour of the tie should not be the same as that of the shirt, while the foreground of the tie should contain the colour of the shirt and thereby "pick up" on the colour of the shirt. Ideally, the tie should also integrate the colour of the suit in the same way. Generally, simple or subdued patterns are preferred for conservative dress, though these are terms with a wide range of interpretation. During the late 1990s and early 2000s, it became popular to match the necktie colour with the shirt (a "monochromatic" look popularized by TV personality Regis Philbin) or even wearing a lighter coloured tie with a darker shirt, usually during formal occasions. A light blue shirt with a blue tie that is darker in its colour is also common.
Knot: Some of the most common knots are the Four-in-hand, the Half-Windsor, the Windsor (or Full-Windsor), and the Shelby or Pratt. A Four-in-hand, Half-Windsor, or Windsor is generally the most appropriate with a suit, particularly by contemporary guidelines. Once properly knotted and arranged, the bottom of the tie can extend anywhere from the wearer's navel level, to slightly below the waistband. The thin end should not extend below the wide end, though this can occasionally be seen to be acceptable with thin ties.
Alternatives: In the 1960s, it was fashionable for men as well as women to wear scarves with a suit in a tied knot either inside a shirt as an Ascot or under the collar as would be worn like a tie.This style began to fade by the mid 1970s and came back in the 1990s mainly for women. It did however make a small comeback by 2005 and some famous stars wear them. Although some wore scarves back in the 1960s, ties were still preferred among business workers.
