Who Invented American Sportswear? The Real Story and Its Irish Influence

If you wander through St. Stephen’s Green or take a DART to Dun Laoghaire on a crisp Saturday, you’ll spot a clothing revolution you might not even pause to notice: the soft joggers, the preppy polos, those practical parkas—an easy, everyday style that owes more to American sportswear than you’d guess. Here in Ireland, with all this rain and the need for comfort walking the grey-brick streets, these sporty staples have quietly muscled their way into our daily routines. But have you ever wondered just who actually invented this look we take for granted? Well, the story isn’t as straightforward as you’d think, and surprisingly, there’s a whisper of Irish connection running through the story of American sportswear’s rise to fame.

The Birth of American Sportswear and Who Actually Started It

Roll back the calendar to early 20th-century America, and the wardrobe was a very different beast. Women especially were trapped in stiff tailoring, corsets, and fabrics that did little to suit an outdoor lifestyle. The real turning point happened in the 1920s and ‘30s, with social shifts echoing across the Atlantic. American designers began to spot what people actually wanted: clothes you could move in, not just pose in.

Claire McCardell’s name pops up first for a very good reason. In the 1940s, while Chanel was making waves in Paris, McCardell broke rules in New York—introducing the “popover dress”, ballet flats, and relaxed silhouettes perfect for biking to work or nipping down to the shop. Some even call her the godmother of American sportswear. Yet, behind every household name in fashion, there’s usually another genius nudging the change along—think Bonnie Cashin and her love for practical pockets, or Norman Norell who loved a neat, clean line.

Now, was there a single inventor? Not really. What’s uniquely American about sportswear is how it grew from the street up, not the catwalk down. Instead of haute couture, it was about making style accessible—starting with blouses, A-line skirts, roomy jackets. Some credit John L. Sullivan (yes, an Irish-American) for his influence: as a boxer who became a folk hero in early 20th-century America, he helped popularise athletic silhouettes. It’s that hybrid of comfort and casualness that found its way, many decades later, into Irish dressing rooms from Malahide to Cork.

And then sport itself ramped things up. Tennis, golf, rowing—fashions designed for function found favour everywhere. As Hollywood icons like Katharine Hepburn and Paul Newman gave these pieces a glamorous twist in films that screened in Galway cinemas and local community halls, Irish tastes adapted. Shops like Brown Thomas and Arnotts started stocking American brands in the ‘70s and ‘80s as Irish shoppers wanted a slice of that easygoing lifestyle—and ease of movement for our changeable weather.

Irish Take: How American Sportswear Won Over Ireland

Irish Take: How American Sportswear Won Over Ireland

What makes American sportswear feel so at home on Irish backs? The first thing is how it cheats the weather. In Dublin, where rain can hit you sideways by surprise, windbreakers and lightweight waterproofs are a game changer. Irish designers have long tweaked this style: look at Orla Kiely’s playful prints on retro-inspired coats, or the effortless layering pieces from Avoca. Even O’Neill’s, that age-old Irish institution of GAA kits, has pivoted toward leisurewear—think hoodies and track pants as common on South William Street as on the training pitch in Buncrana.

Another appealing bit for those of us living here? Sportswear’s knack for blending in anywhere. You can walk the Cliffs of Moher in a puffer gilet and then pop into a pub with only a quick change of your trainers for boots. Irish workplaces, especially outside the financial core of the city, have also taken a turn for the casual, with polo necks, fleeces, and practical trainers a daily sight on public transport and in coffee shops from Limerick to Sligo.

This cross-over between American roots and Irish needs is easy to spot in any local gym or soccer pitch. We’re quick to embrace global trends but always add a twist. American brands like Nike and Under Armour are everywhere—but so is the local vintage wave, with retro Adidas and even rare American college sweatshirts popping up on George’s Street Arcade. In fact, the popularity of charity shops and vintage stores (like Dublin’s Siopaella or Cork’s Miss Daisy Blue) means Irish style often mixes stateside influences with timeless classics, creating something casual but never boring.

Don’t forget, too, how sportswear’s egalitarian spirit sits well with Irish cultural leanings. There’s little snobbery about comfort here. At Electric Picnic or along the Phoenix Park cycle lane, you’ll find the same crowd in joggers and rainproof jackets, regardless of whether they’re heading home to a penthouse or a student flat. That relaxed, community-sharing approach is pure American sportswear ethos, reshaped for Irish living.

Looking ahead, the trend isn’t slowing down. With more remote work and people swapping long commutes for strolls along the Liffey, demand for comfy, stylish gear keeps surging. Irish startups are taking note. Take GROWN, for example—this Wicklow-based brand marries sustainable design with unfussy silhouettes, using recycled materials and plant-based dyes. It shows how Irish design is picking up where American sportswear left off: focusing on utility and environmental impact.

If you’re keen to update your wardrobe Dublin-style, the tips are straightforward. Stick with breathable layers, opt for colour pops in accessories, and don’t be afraid to pair those sporty trainers with a Donegal tweed blazer or a classic wool scarf. Fashion always loops, and right now Irish shops are brimming with crossover pieces blending American ease and Irish heritage.

And there’s plenty of inspiration at home. Watch the blend of streetwear and classics during the All-Ireland finals or the Women’s Mini Marathon—Irish fashionistas aren’t shy about mixing everything from American varsity jackets to practical rain capes. Practicality comes first, but personality isn’t far behind.

Looking for the best buys? Brown Thomas, Arnotts, and BT2 all stock a range of sports-casual brands—while smaller labels like Human Collective and Fourth Arq are worth scouting for Irish takes on the trend. Even Irish fashion weeks and pop-up events in Belfast or Galway regularly feature new interpretations of the American sportswear look.

So next time you throw on those joggers for a coffee run or grab a water-repellent shell before facing a Wicklow drizzle, you’re not just dressing for Ireland’s famous weather. You’re part of a story that started with American rebels but belongs just as much to Grafton Street as to Fifth Avenue.
