Dressing for work these days can be very confusing; especially in a business casual environment. And one question I hear all the time is how casual is too casual? For men the answer is simple. No collar is too casual. The collar is the key element for a business wardrobe, whether you are dressing in a casual or formal business environment. It draws attention to the face and adds a bit of tailoring even to an untailored look.
Depending on the industry, environment and your goals, this can take many forms or a combination of garments worn together. A sport coat, suit jacket, dress shirt, polo shirt, mock or turtle-neck all fall into this category.
