How an All-Dark Outfit Instantly Elevates Men’s Smart Casual Style
Smart casual is one of the hardest dress codes to get right.
Casual outfits are easy — t-shirts, sweatshirts, sneakers.
Formal outfits are clear — button-down shirts, jackets, dress shoes.
But men’s smart casual style sits right in the middle. And pulling it off without a buttoned-up shirt can feel tricky.
That’s where an all-dark outfit comes in.
When done properly, dark tones create a clean, elevated look that feels intentional — not overdressed, not sloppy.
A Dark Sweater Is the Foundation of Smart Casual
A well-fitting sweater in a dark colour is the easiest way to upgrade a smart casual outfit.
I personally like merino wool sweaters for everyday wear. They’re thinner, breathable, and easy to pack for travel — perfect for carry-on trips.
But if you want to take things up a notch, a dark cashmere sweater does something special.
Cashmere adds quiet structure and refinement, allowing you to skip the buttoned shirt altogether. In fact, don’t wear one underneath — just a clean undershirt.
The sweater shown above is from Suitsupply. They’re a bit pricier than my usual picks, but they’re my go-to for suits, and their knitwear quality is consistently strong.
Why Black Denim Looks More Polished Than Blue Jeans
Dark blue jeans are a wardrobe essential — no question.
But black denim quietly elevates an outfit in a way blue jeans can’t. It sharpens the silhouette and pushes the look closer to formal without becoming dressy.
The jeans pictured are the Levi's 501 in black, with a button fly.
To me, the 501 remains one of the best value-for-money jeans available. The cut is timeless, the rise works for most body types, and the button fly adds a subtle old-school character.
One tip: wash black denim inside-out. It helps preserve the colour and keeps the jeans looking sharp longer.
Accessories matter more when your outfit is minimal.
A black leather strap watch is the final piece that ties an all-dark smart casual outfit together.
The watch shown here is the Hamilton Murph 38mm, made famous in Interstellar, directed by Christopher Nolan.
Originally released in 42mm, Hamilton later introduced the 38mm version after fans asked for a more wearable size. It fits most wrists better and feels more versatile for everyday wear.
It’s understated, functional, and carries just enough story to make it interesting — without being loud.
Why an All-Dark Outfit Works for Men
An all-dark outfit works because it simplifies everything.

Cleaner lines
