On the two-tone weave behind one of menswear's most distinctive looks, why it photographs the way it does, and how to wear it without overdoing it.

Every man who's ever been to a wedding, a jazz club, or a Sunday service has seen a sharkskin suit — even if he didn't know the name. It's the suit that looks charcoal from one angle and silver from another. The one that seems to move under the light while the man wearing it stands still. It's been a fixture of American style since the 1950s, and it remains one of the most asked-about fabrics at CCO. So here's the full explanation.

What sharkskin actually is

Sharkskin has nothing to do with sharks. The name comes from the fabric's smooth, faintly iridescent surface — a texture that reminded mid-century tailors of the animal's skin. What produces that surface is the weave: two different-colored yarns, typically one light and one dark, woven together in a tight twill so that the color you see depends on the angle of the light hitting it. Look at a black sharkskin suit head-on and it reads black. Turn slightly and the lighter yarn catches, and it reads charcoal, or gunmetal, or silver. That shift is the whole point.

The effect is subtle in daylight and pronounced under artificial light — which is why sharkskin has always been an evening fabric first. Under the lights of a reception hall, a stage, or a restaurant, a sharkskin suit does something a flat wool suit can't: it has depth. It looks like it cost more than it did.

"Look at it head-on and it reads black. Turn slightly and it reads silver. That shift is the whole point."

Sharkskin vs. sheen: the distinction that matters

A common misconception is that sharkskin means shiny. It doesn't — not exactly. A true sharkskin has a two-tone weave that creates iridescence; a cheap "shiny suit" has a single-color fabric with a surface finish that reflects light uniformly. The difference is visible up close and obvious in photographs. Sharkskin shifts. Shiny glares. If you've ever seen a suit that looked plasticky in flash photography, that was sheen without the weave. Genuine sharkskin — even in a poly-rayon blend, which is what most modern sharkskin suits are made from — has the two-yarn structure that gives it dimension rather than glare.

CCO's sharkskin collection spans Vinci, Tazio, Statement, Royal Diamond, and Apollo King, and all of them are built on the two-tone weave. At the restrained end, the Tazio 3-piece slim fit solid sharkskin is the reference point — a 2-button notch lapel, 5-button vest, and a two-tone that reads as expensive rather than flashy, in ten colors from black and dark grey to champagne and burgundy. At the bolder end, Statement's sharkskin suits push the shine further and pair it with fashion-forward cuts.

When to wear it — and when not to

Sharkskin belongs to the evening. Weddings, receptions, formal dinners, church services, nightlife, milestone celebrations — anywhere the lighting is artificial and the occasion has some ceremony to it. It's a black-tie alternative when a tuxedo feels like too much, and it's the suit that separates a man from the room full of flat navy and charcoal at a formal event.

Where it doesn't belong is the daytime office. Under fluorescent lights and in conservative business settings, the shift reads as too much — not wrong, but noticeable in a way that a boardroom rarely rewards. Sharkskin is a suit for occasions, not for Tuesdays. Treat it that way and it earns its place in the wardrobe immediately.

How to style it

The fabric is already doing the work, so everything else should get out of its way. A crisp white or black dress shirt. A solid tie or no tie at all — patterned ties fight the weave. Black or dark brown leather shoes with a clean profile. If you want an accent, a single pocket square in a solid color is enough. The rule with sharkskin is the same rule as with any statement fabric: one statement per outfit. Let the suit be it.

Fit matters more with sharkskin than with matte fabrics, because the light shows every line. A slim or modern fit keeps the silhouette clean and lets the two-tone effect play across a smooth surface. Excess fabric bunches, and bunched sharkskin catches light in the wrong places. That's why the Tazio slim fit above works as well as it does — trim through the body, flat-front pants, nothing for the light to snag on. For the man who wants a bolder cut, the Vinci double breasted sharkskin pairs the weave with a six-button peak lapel jacket and an adjustable waistband — the most commanding version of the look in the collection, in blue, green, purple, and mocha.

Common questions

Is sharkskin a type of wool?
No — sharkskin is a weave, not a fiber. It can be made in wool, silk, or synthetic blends. Most modern sharkskin suits, including CCO's, use a poly-rayon "wool feel" blend, which is lightweight, wrinkle-resistant, and holds the two-tone effect well.

Is a sharkskin suit formal enough for a wedding?
Yes. It's one of the most popular wedding suits at CCO precisely because it reads as elevated under reception lighting. For a black-tie-optional wedding, a black or charcoal sharkskin 3-piece is a strong tuxedo alternative.

What colors does sharkskin come in?
Black, charcoal, grey, and navy are the classics. Brown, blue, and bolder fashion colors are available in the Statement and Vinci lines. Darker bases show the two-tone shift most clearly.

How do I care for it?
Dry clean only. Hang it on a wide-shouldered hanger and steam rather than iron — direct heat can flatten the weave and dull the effect.
