Business Casual for Men, Explained by a Club That Draws the Line Every Day

Business casual for men is a collared shirt, tailored trousers, leather shoes, and a jacket or knit when the room calls for one, with no tie required and no suit expected. Jeans, t-shirts, shorts, and sneakers sit outside it. It is the office standard between a suit and a weekend, and it passes any smart casual door.

The phrase gets typed into a search bar most often the night before something. A private club is a fair place to ask, because a club applies a written code at its dining room door every day it is open. The Brantford Club, at 98 George Street in Brantford since 1898, publishes one. It says smart casual, which is where business casual gets tested most often.

What is business casual for men?

Business casual for men is the dress standard of a working day that does not require a suit. Merriam-Webster defines it as “a style of dressing for white-collar employees that is less formal than traditional business attire,” and the definition fixes the phrase to the office. In practice it is a shirt with a collar, trousers with a crease or at least a proper waistband, leather shoes, and one layer over the shirt if the room or the season wants it. A man dressed this way passes a smart casual door without thinking about it. A man in a good knit and dark jeans may not pass an office that asked for business casual, and that asymmetry is the whole subject.

The Four Parts: Shirt, Trousers, Shoes, the Layer

Every business casual outfit is four decisions. None of them needs a brand name; the categories do the work. The same four decisions run through business casual as a woman wears it, where a skirt or a day dress can stand in for the trousers.

Business Casual Beside Smart Casual and Business Formal

The three codes sit on one line, and most confusion comes from reading two of them as the same thing. The table sorts them by the garment that decides each one.

The Five Rooms Where the Phrase Is Read

Business casual is the same four parts everywhere; what changes is how strictly a given room reads them. The office is the room the phrase was written for. Read it at the middle of the range on an ordinary day (collared shirt, chinos, leather shoes) and at the top on any day with an outside guest, when the jacket comes off the back of the chair. The client lunch reads it at the top by default: a jacket, dress trousers rather than chinos, a tie in the pocket if the client is the kind who wears one. The Brantford Club keeps a room for this lunch, its Small Boardroom, eight seats and a fireplace, and a blazer over an open collar is dressed exactly right for it.

A club dining room is where business casual meets smart casual, and the Club’s own published dining room code is the worked example. Its dining room code, quoted exactly: “Dining Room dress code is ‘Smart Casual.’ Collarless t-shirts, shorts, ripped jeans and hats are not permitted.” Every item on that list was already out of business casual, so a man dressed for a client lunch clears the dining room easily. The reverse fails: dark, unripped jeans and a knit pass the dining room by the Club’s own list and would not satisfy an office that asked for business casual. The Journal has a separate guide to smart casual for the evening side of that line.

The conference reads it loosely on the floor and strictly at the dinner: chinos and a knit for the sessions, the jacket back on for the evening. The first interview reads it one notch above whatever the posting said: the jacket, the dress trousers, no tie, and the most formal shoes you own.

The Mistakes Men Make With Business Casual

The mistakes are few and they repeat. The most common is reading “casual” as the operative word and arriving in the polo, jeans, and sneakers that would have passed at a barbecue; the operative word is “business,” and casual only modifies it. Next is the orphaned suit jacket worn over chinos: suit cloth is finer and shinier than jacketing, and the mismatch reads across a room. Then the shoe, where a good shirt and trousers are undone by the running shoe that was comfortable in the car. Fit undoes the rest: trousers pooling on the shoe make a well-chosen outfit look borrowed, and a tailor charging for two hems fixes more than a new wardrobe would. The hat is the last, and the Club’s policies name it in both rooms.

Where the Phrase Comes From

Business casual is a North American phrase, and older than most people assume. Merriam-Webster gives its first known use as 1968, in the sense the dictionary still defines. The codes that used the phrase spread through offices later in the twentieth century, as companies loosened the suit for part of the week and then for all of it, and the term settled into job postings and handbooks. The Oxford English Dictionary carries an entry for the phrase as adjective and noun; its record sits behind a subscription and is not quoted here. The Journal’s earlier piece on club dress codes covers the neighbouring phrases.
