Maybe it was the unusual high-pressure weather system, what Kanye West called “crazy lucky weather” — constant light breezes ruffling the umbrella pines, armadas of seven-story clouds sailing across the skies high above the old stones of Florence.
Or maybe it was Matteo Renzi, Italy’s new, young prime minister, breezing into town to deliver a $2.7 million cash infusion to Pitti and a message of Italian unity to the scores of manufacturers, 1,165 exhibitors and the many thousands of international press and buyers crowding into this fabled city for the men’s wear fair Pitti Uomo.
Whatever the cause, optimism was the tone of an event that, while ostensibly only a trade fair, tends to be a bellwether for the men’s wear industry.
Much more than seasonal trend-setting takes place at Pitti Uomo; a mood is established and for the past four days here, it has been one of optimism measured by the extent that men are dressing up again.
Still digging itself out — like all fashion — from the economic doldrums and the lingering drag that casualization has had on creativity, men’s wear seems on the brink of some hopeful changes. If not exactly the dawn of a sartorial Renaissance, we are quite possibly entering the Age of the Natty Fellow.

















He is everywhere at the Pitti enclave and throughout Florence, wearing snug trousers that show off some ankle, a lightweight cotton blazer so fitted it leaves no margin for Twinkies, shoes with proper hard soles, and most of the ensemble — shoes included — in assertive colors such as cobalt blue.
Oh, and he is probably wearing a waxed mustache, a Gabriele d’Annunzio beard and a straw boater.
Does anyone remember Casual Friday? Hoodies and sneakers? Mark Zuckerberg? The inexorable march of heritage brands and artisanal everything has had an unexpectedly affirmative effect on men’s dressing — or anyway it has among the early adopters one finds here. The Natty Fellow’s style is a visual amalgam of “Mad Men,” the New York retailer Freemans Sporting Club and Joe E. Brown in “Some Like It Hot.” That the Natty Fellow himself is likely too young to recognize two out of three of those references matters little. What he doesn’t know, Google Image will provide.










As a result, all kinds of seemingly anachronistic trades were highlighted here. Traditional shoemakers from the English county of Northamptonshire made a strong showing. So, too, did Neapolitan perfumers, Sicilian barbers, venerable Swedish shirtmakers. Even the producers of a special Japanese shoe polish showed up at Pitti, bringing along a shoeshine expert, Hiroaki Mitsuhashi, to demonstrate how he achieves a softly lustrous shine by buffing with the palm of his hand.
At a pop-up barbershop installed by the century-old barber supply company Proraso in the fair’s main pavilion, a heavily tattooed Roman barber named Cosimo Di Gorga applied hot towels to volunteers before cleaning up their whiskers with his straight razor. As it happened, few of the takers were smooth-cheeked, lavish growths of facial hair being another notable Pitti Uomo trend.
Behind the apparent quaintness of all that revivalism there is real local and global economic significance: “One by one, the lights are going back on in little factories,” said Alison Hargreaves, head of publicity for Grenson shoes, whose booth at the Touch pavilion was crowded with buyers drawn to newly reimagined classics that appeal to influencers like Nickelson Wooster, the Instagram style hero known in the blogosphere as the WoostGod. “At the moment, I’m obsessed with them,” he said.

A generation that grew up wearing jeans and sneakers has some catching up to do, according to Stefano Tonchi, the editor of W magazine and curator of a specially commissioned installation at Pitti Uomo titled “De’ (Millennials) Costumi.”
“The codes are being rewritten,” said Mr. Tonchi, whose exhibit took as its inspiration a timeless book of etiquette for young men, created in the 16th century by the Florentine Giovanni Della Casa. “First you learn the rules and then you can break them,” Mr. Tonchi added. “Well, maybe not all the rules: Signore Della Casa said, ‘Don’t stick your hands in places you keep covered.”’ Advice like that has lost no relevance since it was written.
Fascinating things happen where rules are torqued, when rote codes meet innovation. Take the capsule collection that Pharrell Williams’s Bionic Yarn created in a partnership with G-Star RAW jeans. Using fibers spun from recycled plastic waste gathered from the world’s oceans, they produced jeans that both look cool (Mr. Williams’s Otto the Octopus logo is incorporated subtly into the weave) and help humans “come together for Big Blue,” as Mr. Williams noted in a written statement.





Consider another capsule collection, this one generated by the pairing of Kazumasa Kobayashi, designer of a Japanese cult bicycle and bike wear, and Spiewak, a 110-year-old U.S. label founded to provide stevedores on the Brooklyn waterfront with work clothes and now owned by a Swiss company. From that collaboration came a gunmetal gray bomber jacket detailed with such precision that its zippered front opens to reveal an inner zippered half lining of mesh, a way of keeping covered and ventilated as you fly around the city on your fixed-gear bike.
“You know, there is more humor in physics than fashion,” said Sebastian Dollinger, the 30-year-old designer for Eton, a Swedish shirtmaker founded in 1928. Mr. Dollinger was referring his own humorous approach to such stodgy notions as a neutral, “masculine” palette.
“I wanted to have a lot of color” in the collection, he said of shirts patterned with the Eton version of the Mod micro-florals seen everywhere at the fair. “Flowers are an easy and fun way to use a lot of colors and maybe make people smile.”





















No one at Pitti Uomo confused playfulness for a lack of seriousness; food, furniture and fashion account for nearly a third of Italy’s export economy. “I don’t know whether it’s because of Renzi,” said Raffaello Napoleone, the show’s innovative chief executive and an increasingly important figure in Italian fashion, referring to the country’s dynamic young prime minister, formerly the mayor of Florence. “But our exhibitor and attendance numbers are up substantially over last year, so we are sensing a mood of optimism.”

That Pitti Uomo provides a forum not just for industry heavy-hitters but also for tiny niche brands, startups and unlikely collaborations is a large part of its appeal to the thousands of international buyers who descended on Florence, filling its restaurants and driving up hotel prices. “I love Milan,” said a buyer for a prominent retailer, referring to the men’s wear shows beginning Saturday in that city. “But at Pitti you see the trends in real clothes real guys are actually going to wear.”
You see designers such as Matteo Gioli and Veronica Cornacchini, two young hatters that got into the business by apprenticing themselves to traditional Florentine milliners. “We started making hats for ourselves and then for our friends and then the friends of friends,” said Ms. Cornacchini. And now Super Duper hats are sold at Barneys New York.
Their best seller, the Hobo Hat, is as good an example as any of the prevalent spirit of adaptive reuse. “We 
thought it was boring that the only hats you could find for traveling were rolling hats,” said Mr. Gioli. Consulting vintage images of the itinerant railway track-layers known as gandy dancers, the partners came up with a hat intentionally designed to be squashed, its rumpled crown part of the charm.
Consistent with a spirit of cross-pollination that has characterized Mr. Napoleone’s tenure as head of Pitti, certain Super Duper styles come lined with Japanese high tech fabric, introduced to the pair by fellow exhibitors from a label called Norwegian Rain.
“In Norway, it rains two days out of three,” explained T-Michael, a former tailor who designs this line of elegantly severe raincoats. “We met Matteo and Veronica at Pitti and thought that meshing their Florentine tenderness with Norwegian functionalism would be a brilliant idea.”
And it is.
