by MAURICE TERZINI, owner of Sydney institutions Neild Avenue and Icebergs—and no stranger to the finer things.

Maurice Terzini is a dominant—and stylish— presence amongst Sydney's gastronomic elite. Known for their authentic dishes, his Mediterranean-influenced venues continue to grow in stature.

Nothing looks sharper than a crisp white shirt. It'll punch on from office to cocktails and work with anything you throw at it. It'll make your tan show, too. The right shirt makes you stand a little straighter, walk a little taller—even feel invincible. Why settle for less?

Collars come in an impossible array of varieties—but there are two you should be focusing on. The semi-spread is the best option for today's man: strong, progressive, with a hint of classic style.

If, say, you're wearing a power suit, give it a worthy collar: full spread. Crucially, match it with a with some width.

Every man's style starts somewhere. Calvin Klein launched his label in 1968—in a hotel lobby. With $10,000 and an initial collection of humble outerwear, his sartorial vision went global through a range of lines, most famously underwear. All-American fashion has been dictated by this style master for decades. Just as well, that $10,000 became more than $700 million when he sold his company in 2002. Rely on CK for masculine edge with effortless cool.

With a CK dress shirt you can pull-off classic style, with panache. The cut is slimmer, but keeps a timeless spread-collar—the perfect upgrade for whatever's on your back. Slim down and button up, gents.
