In the race to be the belle of London’s summer 2025, there can be no denying Gen Z darling Mia Regan — model, influencer and hiking fanatic with long limbs and an impressive insouciant energy — is a front runner. And she appears to have gas in her tank to power through August, too.
Obviously stellar looks have helped the 5ft 10in 22-year-old ascend from a netball-filled childhood in Chippenham to playing attack on the court of high society. But for Regan, known to her almost 600,000 followers as Mimi Moocher, strategic management, controlled access and a down-to-earth persona have ensured her upwards career trajectory. It began at 14, when she was scouted at the Birmingham Clothes Show, and soared thanks to her high-profile, five-year relationship with Romeo Beckham, the middle son of David and Victoria. They met while at school; he studied at Millfield, while she was an hour away at the public Royal High School of Bath, where she had a sports scholarship.
Over the years Regan has successfully cultivated her own personal brand based on lucrative partnerships (On, Miu Miu, Calvin Klein), catwalk shows (Emilia Wickstead, SS Daley) and high-profile events (from London premieres to Paris Fashion Week’s front rows).
And Regan might well be glad that she stepped away from the Beckham brood for good in February last year, ensuring her comfortable distance from their long, hot summer of discontent, riddled with reports of family feuds.
Today she is about to jet off for “a quick trip” to Hamilton Island, Australia, to host a party marking the launch of the H&M summer clothing line she designed. Just another day for Regan in what has been a rapid-fire few months. “The summer for me starts after that first May bank holiday,” she says, her mauve fringe tousled and skin glowing. “We do a big family and friends camping trip in Cornwall, and then festival season begins.” Anybody digitally literate would have struggled to miss Regan at Glastonbury in June, as she led best dressed galleries from British Vogue to the Standard. She goes every year, but if you didn’t see her in the VIP area, it’s because she doesn’t like it there. “I give my wristbands to my parents,” she says. “I love being in the normal crowd with my mates.”
Her uniform this year was plucked from her H&M collection, out in the UK today, which she designed to be “practical and comfortable”, taking fans from Ibiza’s beaches to London’s parks. An itty-bitty bikini top (£27.99) was her Glasto go-to, and is the most likely item from the capsule to become a status symbol among the in-the-know east London style set.
“It’s sparkly but not itchy, which was important,” she says. “The burgundy and orange colours are taken from an old photo of my grandma wearing something similar, and the bikini bottoms (£22.99) also have a little belt detail to keep things interesting.” Cargo mini shorts (£44.99), capris (£54.99) and trousers (£64.99) could also be spotted in her looks at Worthy Farm.
Large, printed silk scarves and a capacious, beige shoulder bag with sailing-knot handle complete the design stint. “It’s big enough to be a beach bag, but you could also use it for travel or daily life,” Regan says. “All of it can be worn together and styled up or down. The capris can work for a daytime walk and then you can switch to the silver top and kitten heels for the evening.”
Kudos must go to Regan for bagging the design role for an H&M collection, which so far has been a task reserved for top fashion designers, from Karl Lagerfeld to Stella McCartney. She is quick to mention she is the first talent to work with the brand in this way. And while the details have been kept quiet, one can assume Regan is smiling on the way to the first-class lounge at Heathrow for good reason.
The rest of her summer has been as enviable, from pilates retreats in Crete and cycling holidays in Montenegro through to a jaunt at Wimbledon dressed in Thom Browne and head-turning outings to society events: see, her arrival to the Royal Academy summer party wearing a trompe l’oeil naked dress by Central Saint Martins graduate Petra Fagerström.
When at home — currently, she lives with a childhood friend, Florrie, in east London “which reminds me of Bristol, and I grew up near there. It’s got so much energy and always things happening” — she keeps a tight routine. “I start the day with a swim in the reservoir, a lido, or the ponds, then probably go to a park, get a nice drink or snack, meet friends,” she explains. When she doesn’t have a modelling job, “I’ll walk everywhere with headphones in and sometimes stop somewhere to read a book. The last I read was Animal Farm.” Her take? “It feels very topical,” she says.
“Being outside has been part of me since I was little — my parents always took us biking or camping, and we spent a lot of time in Wales and Cornwall,” she adds. “When you grow up like that, you either love it or reject it, and I completely love it.” Her parents are Des, a former fundraising manager for the Wiltshire Air Ambulance, ex-Royal Navy radio operator and proud father — his Instagram handle is @mimiesdad — and Helen, who is regularly seen by Regan’s side at events and fashion shows. She has one brother, Finn, who is “very clever” and works in military defence for BT. “They keep me grounded,” Regan says.
She never drinks too much (“I’m actually very reserved; everyone teases me because I never lose it”), limits her screen time to an hour on Instagram and an hour on TikTok per day (“I try not to overdo it”) and hardly wears make-up (“just maroon mascara, I had bad hormonal acne last year, so I wash my face, moisturise, that’s it”). And it all seems to work.
How does she feel about being labelled an It girl? “I don’t think about it that much,” she says. “But I guess it’s about girls who are doing well and who have something special. Everyone has their own thing, and I respect that.”
The H&M x Mia Regan co-creation is available from July 17th, from £19.99, hm.com
