Whether Your Style Leans More Gen Z or Millennial, You Need to See These 8 It-Girl Summer Outfits
From polka-dot dresses to loose jeans, these eight celebrity It-girl summer outfits are a must-see. Scroll to discover below.
If you looked through the Saved folder of this 26-year-old fashion editor, you’d find a lot of chic outfit inspo. From an abundance of vintage, archival pieces (Chanel's Ladybug heels are my newest fixation) to easy-breezy linen ensembles perfect for the summer heatwave I’m manifesting, my mood board is a style treasure trove. Scrolling through recently, I came to a realisation that almost every single post centres around the outfit of a Gen Z It girl.
Celebrity event wardrobes are full to the brim with enviable fashion finds, and whilst our lives couldn’t be more different (I’m unlikely to headline a tour or host Saturday Night Live any time soon), when you look at their off-duty personal style, it couldn’t feel more… normal. Whether they’re leaning into vintage eras and dusting off prim polka-dot dresses or channelling a WAG in their heyday in an outfit worthy of Victoria Beckham's approval, these fun looks feel perfect for the upcoming warm weather.
I'm in the market for a dash of seasonal outfit inspiration, and the cool girls below were my first port of call. Not only does their style cover every aesthetic we'll see this summer, but their ability to blend the old with the new and the fashion-forward with the pared-back makes them worthy of the It girl title. Having searched through their most recent 'fits, I’ve found eight excellent outfits worth re-creating this summer. Scroll down to discover.
9 Gen Z Outfit Ideas to Re-Create in Summer 2026
1. Hailey Bieber
Style Notes: Whether she’s promoting Rhode or dictating the season's biggest shoe trends, you’ll be hard-pressed to find a celebrity Gen Z adores more than Hailey Bieber. With a personal style that toes the line between pared-back minimalism and fashion-forward It girl, everything from floral appliqué dresses to capris and pointelle tees features in Hailey's summer outfit rotation. And the shoes? Think classic. She's regularly seen in The Row's City flip-flops, with a streamlined shape that makes for the perfect finishing touch.
Shop the Look:
Hailey's De La Vali dress is on pre-order, but Reformation's Naira minidress has a similar vibe.
2. Iris Law
Style Notes: As the quintessential London It girl for Gen Z, Iris Law’s summer outfits blend unexpected textures with eclectic prints and kitschy accessories with the coolest hybrid shoes on the market. Her bold looks feel innately "her", whether she's pairing a pinstriped miniskirt with a fitted, hooded top, or layering a pretty broderie mini over a lilac bikini. Her unique brand of worldly whimsy runs through every ensemble.
Shop the Look:
If you're a fan of pretty classics, Dôen's Patience dress just might be your perfect match.
Rat & Boa makes some of the coolest swimwear around right now.
Shop the matching Clio Bikini Pant (£105).
3. Devon Lee Carlson
Style Notes: To Gen Z as Alexa Chung is to millennials, Devon Lee Carlson needs no introduction. After a chance meeting with Miley Cyrus in 2012 catapulted her to fame, you're likely to spot Devon bouncing from star-studded events like Charli XCX’s wedding to sitting FROW at a Gucci show. As such, her summer style is all about playful, kitchy pieces, and the Gen Z style set adores it. Her recent look in Rome (a gingham skirt, peep-toe kitten heels and 3/4-length T-shirt) is so charming and one you're likely to see replicated this summer.

Peep-toe heels are one of this summer's biggest shoe trends.
4. Olivia Rodrigo
Style Notes: After sending the internet into a frenzy by professing her love of babydoll dresses, what Disney-star-turned-pop-sensation Olivia Rodrigo will wear next is the question on every Gen Z’s lips. On the press tour for her latest album, the ex-London resident channelled her innermost '00s WAG in an FC Barcelona top and low-rise True Religion jeans. With the World Cup mere weeks away, it's a look every stylish, fashionable fan at home and away must see before the games begin.

Adidas has so many cropped football shirts online right now.
Style with pointed-toe boots and a blouse for a casual boho look.
5. Alex Consani
Style Notes: The British Fashion Awards' 2024 Model of the Year, Alex Consani, knows her way around a chic summer outfit. Her meme-inspiring personality might be seriously extroverted, but style-wise, Consani's summer looks couldn’t be more pared-back. As a lover of structural cuts and fashion-forward detailing, her outfits give serious '90s supermodel energy. But it's her recent balloon trousers, loose shirt and peep-toe heel combination during a Parisian excursion that I’m looking to re-create asap.
Shop the Look:
Khaki balloon trousers are one of this season's most popular trouser trends.
6. Sabrina Carpenter
Style Notes: What do Madonna, Barry Keoghan and vintage dresses have in common? Well, Sabrina Carpenter, of course. After shooting to superstardom over the past couple of years, the ex-Disney star is proving to be one of pop culture’s most compelling recent style icons. Expect drop-waists, minidresses, tall heels and lots of sparkle in her tour wardrobe, but well-deserved downtime in T-shirts, loose jeans and ballet flats.
Shop the Look:
I wear these Agolde jeans at least once a week.
7. Billie Eilish
Style Notes: Billie Eilish’s summer style might not be for you; however, we at Who What Wear UK think it's high time we give the singer her flowers for being unapologetically herself. With layered tees and oversized silhouettes becoming Billie's brand signature, this look (pictured above) from her press junket for Billie Eilish – Hit Me Hard and Soft: The Tour feels decidedly fresh. Be it the divisive lace-detail Prada pumps or the knee-grazing pleated skirt with stockings, it's a look I can already see being re-created by her nonconformist fans.

8. Kylie Jenner
Style Notes: For the stylish Gen Zer, it's impossible to find a celebrity It girl as influential as Kylie Jenner. The youngest member of the Kardashian-Jenner clan has been making waves since the "King Kylie" era (who else could convince a generation of pre-teens that all you need is a lip kit to look like her). Having now evolved from her skinny-jeans-and-logo-mania days, today, her summer style is all about bodycon separates and a cute colour palette. Looking for a casual 'fit for weekends? Try yellow jeans, a white tank top and Maison Margiela ballet flats that are more fun than trainers.

Style under linen this summer.
The OG divisive shoe.
