Suit (clothing)
Suits are not necessarily expensive, because while some may need to be tailored, this is a relatively cheap op, around $20 USD. Casual people suit up less today than in the last century, and presuming a tailor is a specialist, and cannot do it in the 5 minutes it takes you to stand in the mirror, is one common fallacy. Sportscoats are semi-formal clothing, usual for wearing to some offices, but less mainstream for watching a football match. A trend towards semi-casual style (just dresspants) started in the 1960s and 1970s, and has changed the way many people dress. All the same, many high-status men and women do still wear suits.
