Help us out here, Wikipedia darling (I personify my favourite websites, is that weird?).
Sprezzatura is an Italian word originating from Castiglione’s The Book of the Courtier, where it is defined by the author as “a certain nonchalance, so as to conceal all art and make whatever one does or says appear to be without effort and almost without any thought about it.” It is the ability of the courtier to display “an easy facility in accomplishing difficult actions which hides the conscious effort that went into them.”
It's the Italian je-ne-sais-quoi and something that comes naturally to some or takes years of indifferent practicing.
I try to keep my boyish enthusiasm at a minimum, but that still comes down to excited glances, heavy breathing and a manic grin when I see something fabulous.
I try to say "Care?" (or "Currr?") but it's just no use.
When practising the Sprezz I often ask myself, 'what would Francesco Cominelli (Vogue Hommes stylist/ editor) do?'
The man knows how to dress impeccably and has the attitude to match.
"What? This? I didn't spend four weekends scavenging vintage shops on the Rive Gauche to find this jacket, I just tripped over it in my grandfather's attic. Like. Care?"
His secret? A good, high quality man-clutch (mutch)!

He makes it seem so easy! Even a picture of half his torso is chic!
