When former New York City Mayor — and Donald Trump lawyer — Rudy Giuliani’s car got rear-ended in New Hampshire late last month, it was Arthur Aidala who let the world know he was expected to recover.

Giuliani is far from Aidala’s only high-profile friend or client. The criminal defense attorney and managing partner of Aidala, Bertuna & Kamins has worked for everyone from NFL Hall of Famer Lawrence Taylor to Steve Bannon, Harvey Weinstein, Mike Tyson, O.J. Simpson, Roger Ailes, Alan Dershowitz and a slew of other controversial bold-face names.

He’s even become a celebrity in his own right, hosting a radio show nightly in New York, and acting as the legal expert for both Fox and CNN.

With such a high-profile career, Aidala needs to dress the part. But interestingly, rather than opting for super-luxe $10,000 bespoke suits, he still goes to the same neighborhood haberdasher in Bay Ridge, Brooklyn, where he’s been shopping his whole life: Gentlemen’s Quarters.

Aidala, 58, grew up in Bay Ridge in a Sicilian American family to a schoolteacher mother and a lawyer father. He attended Poly Prep school, where he had to wear a shirt, tie and blazer, and was introduced to Gentlemen’s Quarters by his dad. Since then he’s been working with the same owner for more than four decades. “He put me in a blue blazer with gold buttons when I was 12,” he said with a laugh.

Professionally, following in the footsteps of his father — and grandfather, who was also a lawyer — seemed inevitable. After passing the bar, Aidala got his start with the Kings County District Attorney’s Office in Brooklyn prosecuting some of the borough’s worst crimes.

Despite being called the Master of Defense and the Dapper Advocate, Aidala says he’s not really a fashionista. “People have remarked on my sartorial choices, but I open my closet, look at the weather and think about what’s on the agenda for the day. In federal court, you dress a little bit more conservatively than you do in state court. If I’m going to be on Fox at 5 in the morning, which is the local TV show, I could be a little bit more flamboyant, whereas at CNN, which is national, you know some people from Utah are watching, so I might dial it down a little bit,” he said.

He’s also conscious of the time of the year. “Is it November, when we’re talking about oranges and browns, or is it May, when you’re talking pinks and florals? There’s not a tremendous amount of foresight.”

With a three-year-old child at home, the father of three said “there’s not a plethora of time to make design choices.” And he doesn’t follow fashion trends. “I’m not up on the latest fashion, so I have no problem going into the end of the summer season sale and buying a suit that’s going to go in my closet until next summer. If the lapel is an eighth of an inch smaller next year, I’ll suffer through it.”

He said that while Gentlemen’s Quarters remains his go-to spot, he’s not against searching for sales elsewhere as well. “There’s a store on Madison Avenue called Eredi Pisano — they have one in Rome as well — but their end of the season is 75 percent off. So you pick up something that’s 1,000 bucks and it’s $250 — I’m OK with that, I don’t need that blue blazer so badly.”

He recalls being recommended to Zohreh, a high-end men’s store on 54th Street “where the New York Yankees and the New York Rangers get their clothing,” he said. “I was going to treat myself to a custom suit and the owner measured me and went over to the rack and pulled out a 44 regular. That was a game changer.”

So while Aidala may not have had to buy a bespoke suit for himself, he takes some of the other lawyers in his firm to Zohreh for custom suits for Christmas. “Most people need some sort of customization but I don’t.”

In terms of brands, it’s not Brunello Cucinelli, Brioni or Zegna that he’ll be found wearing. Instead, he opts for Vista, a brand popular at Gentlemen’s Quarters. “And I don’t pooh-pooh a good Men’s Wearhouse or Jos. A. Bank suit, especially light ones, which I’m known to stain, and I don’t want to stain anything obscenely expensive. For me personally, it’s how you carry it, and accessorize it and the confidence you exude when you wear it.”

That being said, he also won’t spend a lot of money on ties. “If I spend $50, that’s a lot. In Florence, on the edge of the Ponte Vecchio, I bought a tie for 20 euros. I know there are people who spend hundreds of dollars on ties. I don’t condemn them for doing it, but I don’t think it’s necessary. One of the ties that I wear that people compliment me on, I literally bought on the corner for $2 because I stained the one I was wearing. Sometimes I get ties as gifts and people leave the price tag on, maybe intentionally. Gucci ties for $450? I’d rather go away for the weekend.”

One place that he does indulge himself — a bit — is his footwear. “Whenever I pack to go to Italy, there’s always room in my suitcase for at least two pairs of shoes to come back,” he said. “But I literally have shoes that I bought in Italy 25 years ago that I still wear. They are just well made, and I think taking care of your feet is very important. I walk a lot — I do 10,000 steps a day without going to a gym.”

But like his suits, not even his shoes are all that expensive. Aidala said he often shops in Milan and Florence and picks up $400 shoes, not $3,000 custom models that many other executives sport.

Aidala has also become known for his hats. “I wear a fedora almost always,” he said. It started out as a necessity because he lost his hair at a young age and was “one of those guys walking around in a suit and baseball hat. I was young and this young woman I was spending time with said I looked too good to be wearing a Yankees hat.”

So he visited the venerable JJ Hat Center on Fifth Avenue and bought hats for winter and summer. He said the hats have become his trademark when he’s on television or addressing the media at press conferences and his social media team has instituted Fedora Friday, where they showcase Aidala in his different toppers.

While fedoras may not be required, Aidala does insist that his staff dress in suits. “If you dress like a lawyer, you’re going to feel like a lawyer, think like a lawyer, act like a lawyer and be a better lawyer. If you’re a client, you want to put your trust in someone who knows what they’re doing. And I think if someone dresses in a certain way, it gives off the impression that they’re paying attention to details. It may sound a little old fashioned, but I think it gives people a degree of confidence.”

That also goes for the courtroom. “Whether it’s the client, the opposing counsel, the judge and, most importantly, the jury, you only get one chance to make your first impression,” he said. “From my watch to my pen to my pad to my briefcase, there’s such a delicate balance of showing a jury that you’re paying attention to detail.”

But Aidala is careful not to go overboard. “I don’t have any expensive, fancy watches and I don’t really wear cuff links.” His timepiece of choice is a rose gold Maserati watch he picked up in Capri because he liked the color.

One thing he’ll never do when he’s holding a press conference is wear sunglasses. “It looks like you’re hiding something,” he said.

But while his image may be of utmost importance, Aidala likes to have a little fun too. If he hadn’t become a lawyer, he would have become an actor or singer. “I was a thespian,” he said, adding that he was in a band in high school and acted in college but ultimately opted for a career with more “intellectual stimulation.”

Even so, there are still remnants of his thespian days in his Midtown office where he’s created a Sinatra room: a retreat with a massage chair, memorabilia, a wet bar, record player and big screen TV. 

“I just need a place to chill, maybe take a nap,” he said. “And it became a hangout for everyone from Geraldo Rivera to Mayor [Rudy] Giuliani to Alan Dershowitz. It’s a little tiny sliver of paradise when clients start freaking out and the walls are caving in. You go in there to calm down a little bit. Everyone needs a place to escape.”
