I’m writing this as New York fashion week comes to a close, and it’s been a whirlwind six days of shows and antics. Rihanna kept everyone waiting for almost an hour at Alaïa. Wu-Tang Clan popped up with a surprise performance onboard the Tommy Hilfiger ferry and Luar closed out the week with a front-row appearance by Madonna. As for the catwalks? There was one dominant theme that you couldn’t miss, from chinos to varsity jackets and knitted sweaters: preppy is well and truly back.

This way of dressing originally took its inspiration from Ivy League sports clubs and campuses. It is a trend that is heavily rooted in class and identity and it comes at a time when these issues are at the forefront of American politics, with the 2024 presidential election less than two months away. Politics was also, naturally, a hot topic on and off the catwalks. Prabal Gurung took his post-show bow in a T-shirt emblazoned with “VOTE” on the front and “Harris/Waltz” on the back. Anna Wintour and Jill Biden hit the streets of Manhattan alongside designers including Thom Browne, Michael Kors and Tory Burch as part of a non-partisan voting awareness march organised by the Council of Fashion Designers of America and Vogue. And fresh from her appearance at the DNC, Ella Emhoff, the 25-year-old stepdaughter of Democratic candidate Kamala Harris, was the model and front-row guest of choice for a string of designers including Burch and Coach.

But the preppy trend provided the most food for thought. It feeds into a wider commentary from designers on the American dream and what that concept means and looks like in 2024. Immigration is a key part of the notion, and it also happens to be one of the crucial policies that both US parties are grappling with.

Ralph Lauren, the son of Jewish immigrants who grew up in the Bronx and now has a reported net worth of £5.3bn, is often held up as the embodiment of the term. His picture-perfect spectacle on Thursday night in the Hamptons oozed an old-money lifestyle that is certainly one version of the dream. Speaking at a reception before the show, where waiters clad in white RL polo tops handed out champagne and miniature lobster rolls, the actor Laura Dern mused on Lauren’s version of preppy. “There is always deep iconography connected to America,” she said. “He loves American traditions and family has always been embedded in his stories. It’s always playful and hopeful. With everything going on, to feel hopeful is a nice feeling.”

If Lauren’s world is a version of the American dream as lived by the 1%, Willy Chavarria’s commentary was a little more democratic. Chavarria, who was born in California near the Mexican border, is the son of an Irish-American mother and Mexican-American father. The designer said he wanted to “celebrate immigration and those people who have built the country and are still the backbone of the country”. His show was held in a disused bank on Wall Street, and guests arrived to find a giant US flag hoisted above them and a copy of the American constitution on their seats. Chavarria said he added the accent to the show’s name, América, because this is how the word “is heard through the voice of an immigrant or the child of an immigrant”. The clothes riffed on uniforms – cargo pants and neat button-down shirts – and were said to be a celebration of the workforce. In a nod to farm workers, some wore bandanas wrapped around their faces. “The collection is a story of empowerment,” the designer said. And while Chavarria’s price point is out of reach for most blue-collar workers (trousers cost about £600), it did feel as if he was planting the seed for a new type of American style. “It’s really about the fact that all of us belong, all of us have purpose, and all of us have the ability to make change in this country, especially starting with the vote.”

With an invitation that mirrored the American green card, Off-White’s Ib Kamara was also thinking about immigration. Kamara said he had decided to show in New York rather than the brand’s usual slot at Paris because he wanted to bring the brand, which was founded by the late American designer Virgil Abloh, “home”. Kamara explained that, growing up in Sierra Leone, “America was a dream”. “If you want luxury, you come to America. It’s a dream place. You feel hopeful when you come.”

Stuart Vevers, the British designer and creative director of Coach, who sent Emhoff down the catwalk wearing an “I heart NY” T-shirt, also spoke about hope. “There’s a sense of optimism in the next generation,” Vevers said. “There’s a lot of hope. They’re going to change things.”
