Business Casual used to basically mean sport coat, dress shirt no tie. Today this definition is incredibly nebulous since the vast majority of guys are not wearing ties these days. I believe the key to developing a suitable personal style of business casual involves three things 1) be aware of your environment. The three Fs Antonio speaks about Fit, Fabric and Function all apply here but the main focus is Function. In other words based upon the venue and culture at the event-what one wears when and where to a specific function should be understood by every gentleman attending. 2) intentionality. Be Intentional with your ensemble. For me simply not wearing a tie to the luncheon I attended today might be enough to be business casual-but to me, showing up with a blue OCBD or point color dress shirt, Navy blazer, and grey slacks would feel like I simply ran out of the house and forgot to put on a tie. Consequently to go to a community Luncheon my wife puts on at our church each month then returning to the house to complete paper work -felt like a perfect day to go Business casual. With temps slipping back up to the low 90’s I grabbed a brushed cotton burgundy blazer Orvis duck cloth khaki jeans-cut trousers, Orvis cut and sewn shirt, silk P Square to tie in the colors of the pants and burgundy coat , Indiana Jones Alden Boots and my Borealis dive watch. 3) Consistency, Each of us differ based upon our respective personal style and career. When @Richard Pollock wears a Chambray blue shirt with chinos or jeans that in my line of work too might be too casual to be even be business casual. Contrastingly for Richard, when he is going out on sites his ensemble may be comparatively the same as me wearing a three piece suit if attending a meeting with a group of trust attorneys and a client. He is dressed in his full armor like I and a coat and tie am dressed in mine. (Maybe adding a sports coat over his great Chambray shirt is better comparison to my trust attorney example🤷🏻). The details are less important than the consistency. Richard’s customers and guys he interacts with have become used to him looking sharp and from what I gather when he orders his company logo gear, and chooses classic fabrics, he is possibly the best dressed guy in his meetings. (9 out of 10 times I am as well for my meetings). Point is. Each of us are in our respective business attire. It’s how we interact in our roles-not the garments themselves. So to reiterate his professional attire differs from mine but serves the same function and each of us are pretty consistent. So for me today’s outfit for a business /community luncheon is pretty casual based upon how folks consistently see me through out the day-day after day. (I still had a few million dollars of clients assets in that room😉). This is the consistency part.
