Gentlemen, do you know your collars? - Here's the lowdown on five.

Something that rarely gets discussed when it comes to looking smart as a man is the collar. A subtle wardrobe detail, yet one that can have a profound affect on an ensemble. Get it right for your next interview or big presentation.

Button Down

Once a cornerstone of the Ivy League wardrobe - now a smart-casual staple across the world - the button down collar is the miraculous innovation of the flustered polo players of New England. As such, it does its best work in relaxed, ever-so-slightly-preppy ensembles; and when paired, of course, with a decent Oxford cloth.

The Spread

With clean lines that look great both with a tie and without, the spread collar has dominated business wear for several years now. This cut comes in a variety of "spreads" (the distance between the two collar points), but we recommend opting for a fairly traditional opening.

The Club

The club collar traces its lineage through Victorian stuffiness, Jazz Age revelry and Harvard prep, and emerges out the other side as as rakish as ever. The club can be worn without a tie, but we think it looks best with a silk woven number in between its softly rounded tips.

The Tab

The tie lover's best friend, the tab is characterised by a concealed button at the top of its placket which forms a flattering crease along the body of the collar and pushes the tie knot to the forefront. Oh, and it was also deployed by Daniel Craig for the entirety of the latest Bond romp, and he ended up kissing Lea Seydoux, so...

The Grandad

Stub. Grandad. Band. Mandarin. Henley. Call it what you want, this collar-without-the-collar is your new best friend. Stand it up underneath a crew neck sweatshirt for a twist on the preppy stalwart. Wear it open necked and in linen and look like you've just got back from the French Riviera. Layer it with denim and suede for an artistic, mid-century spin. Hell, you can even drop it under a navy blazer and undo a couple of buttons for a distinguished take on smart-casual. Just get one, quick.
