Business casual is the dress code most men actually get wrong — not because the rules are unclear, but because "casual" gets read as license to under-dress, and "business" gets read as license to wear a full suit anyway. Neither is right. Business casual is its own register, and once you know the formula, it stops being a guessing game every morning.
The Core Formula
Business casual, reduced to its simplest version: tailored trousers or chinos, a collared shirt, a leather shoe, and no tie. A blazer is optional but elevates the outfit toward the more formal end of the spectrum when the occasion calls for it. What's excluded is just as important as what's included — no sneakers, no t-shirts, no visibly casual fabrics like heavy fleece or athletic wear.
The Dress Shirt: Where to Start
A well-fitted button-down in a solid neutral or a subtle pattern is the foundation of the entire look. White and light blue are the safest, most versatile choices; a subtle stripe adds a bit of character without pushing into casual territory. Our Business Casual Dress Shirts collection is built around exactly this need — tailored, breathable shirts that work whether or not a blazer goes over them.
Trousers: The Piece People Get Wrong Most Often
Jeans are not universally off-limits for business casual, but they need to be dark, unwashed, and worn with everything else dressed up around them — a risk most men are better off skipping in favor of tailored trousers or chinos with a clean break at the shoe. Our classic pleated business trousers and the tailored trousers both hold their shape through a full workday without looking stiff.
Layering: Sweater, Blazer, or Both
A knit sweater or cardigan over a collared shirt is one of the most reliable business casual layers — warmer than a blazer alone, and slightly softer in tone. A cashmere-look crewneck in navy or gray works over almost any shirt underneath. Our cashmere-look sweater is built for this exact role, and pairs cleanly with a blazer on top for colder days or dressier meetings.
Footwear: Loafers Over Lace-Ups, Usually
A leather loafer is arguably the single best business casual shoe — more polished than a sneaker, more relaxed than a formal oxford, and correct with both trousers and chinos. Our classic loafers and the more formal business loafers cover the full range from Tuesday-in-the-office to client-meeting-Friday.
The Blazer Question: When to Add One
A blazer moves an outfit up a register without moving it all the way to formal — useful for client meetings, presentations, or any day where the stakes are slightly higher than usual. Keep it unbuttoned when seated and choose a fabric with visible texture rather than a shiny, suit-like finish, so it reads business casual rather than half a suit. Our business blazer jacket is built for exactly this in-between role.
Three Outfit Formulas by Day Type
Standard office day: Collared shirt, tailored trousers, loafers, no jacket needed.
Client meeting or presentation: Same base, add the blazer, swap in business loafers.
Casual Friday: Cashmere-look sweater over the shirt, chinos, loafers, jacket optional.
Common Mistakes
Wearing a full suit and calling it business casual (it reads as overdressed, not put-together). Sneakers, no matter how clean or expensive. Wrinkled or untucked shirts — fit and finish matter more in this register than in a fully casual one, since there's less room to hide behind. And graphic tees or anything with visible branding, which undercuts the whole point of the dress code.
