My dear readers,

It is with a sense of both duty and delight that I turn my attention this week to two paragons of modern male refinement — His Royal Highness Prince Mateen of Brunei and the enigmatic Danial Deen Isa-Kalebic. One, a prince by lineage; the other, a gentleman by cultivation. Together, they are restoring the lost art of dressing with quiet power.

Earlier this season, while nursing a glass of vintage Armagnac in the drawing room, I came across a photograph of the two men — one in a navy wool-blend jacket, the other in a restrained palette of grey and ivory. The image struck me like a passage from Waugh: timeless, precise, and refreshingly devoid of trend-chasing vulgarity. It reminded me, in no uncertain terms, that the highest form of style is not performance, but presence.

The Fit: Neither Shouted Nor Shrunk

What distinguishes both gentlemen — and I say this with the confidence of a man who has commissioned bespoke garments from Naples to Savile Row — is their unerring eye for fit. Prince Mateen’s tailoring, in particular, reveals a majestic understanding of proportion: soft shoulders that evoke Neapolitan nonchalance, paired with a structured silhouette worthy of state occasions.

Deen, meanwhile, brings a continental precision to his dress. I am told he favours layering a white tee beneath a tailored bomber — an approach that, when executed poorly, collapses into adolescence. And yet, in his case, the look reads not as casual, but calculated. It is the fit that saves him — deliberate, unfussy, and precise.

One is reminded of the late Duke of Devonshire’s maxim: “Better a simple garment well-cut, than a peacock’s feather flapping in poor taste.”

Fabric: The Whisper of Wealth

Allow me to be blunt — true elegance never announces itself with logos. It speaks in the grain of the cloth, the breathability of a knit, the way light bends over brushed flannel or double-faced cashmere.

Prince Mateen’s choices often gravitate toward wool-silk blends and textured knits — garments that seem to exist somewhere between formal and poetic. Deen’s choices are equally astute, leaning into tactile layers and natural fibres that hint at old-world craftsmanship. I suspect he owns several pieces made in small European ateliers — not for vanity, but for heritage.

Indeed, when your garments feel as though they were chosen by candlelight in an oak-panelled dressing room, you have arrived.

Layering: The Gentleman’s Game of Restraint

It takes no skill to pile on clothing. But to layer with elegance — to suggest depth without disorder — is an art form. These men understand that harmony of texture and tone is paramount. Their ensembles whisper of early evenings in Montreux, of unhurried travel between capital cities.

I noted recently that Deen paired a cool grey knit under a bomber of alpine green — a combination that echoed the forest edge outside my study just after a rain. Prince Mateen, ever regal, prefers blues in graduated shades, like a composer playing with octaves. Their layering neither overwhelms nor competes. It converses.

The Quiet Confidence of a Well-Turned Heel

No discussion of elegance is complete without a nod to footwear. Here, again, both gentlemen display commendable restraint. Loafers in suede, sneakers in pristine white, soles that tread softly upon parquet and marble alike. No brass buckles. No gaudy contrast. Just intention.

Even their hair — neatly parted, never plastered — reflects an inner discipline. One senses they dress not to be seen, but to honour the rooms they enter.

In Closing: On the Gentle Pursuit of Perfection

As I prepare for a late luncheon at Boodle’s — an affair promising both roast venison and meaningful conversation — I am reminded of something I once heard the late couturier Francesco Smalto say: “Elegance is not created. It is revealed.”

Prince Mateen and Danial Deen reveal much — not just about the changing face of masculine style, but about the values we at GC hold most dear: discernment, lineage, and a refusal to capitulate to the ephemeral.

If you must look anywhere for guidance, look to men like these. For in an age of noise, it is still the whisper that commands attention.

Yours in taste and timelessness,
Harrison Montgomery Blackwell III
