Whether Your Style Leans More Towards Gen Z or Millennial, You Need to See These 9 It-Girl Summer Outfits

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 (the Chanel Ladybug heels are my newest fixation) to easy, breezy linen ensembles perfect for the summer heatwave I’m manifesting; my moodboard is a style treasure trove. Scrolling through my saves recently I came to a realisation—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), 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-dots, or channelling the late oughts in WAG ensemble worthy of Victoria Beckham's approval, these fun looks feel perfect for the upcoming warm weather.

As someone in the market for a dash of seasonal outfit inspiration, 9 cool-girls were my first point of call. Not only does their style cover every aesthetic we typically over summer, but their ability to blend the old with the new, and the fashion-forward with the pared-back, makes them worthy of the title 'It girl'. Having searched through their most recent fits, I’ve found 9 excellent outfits worth recreating this summer. Scroll down to discover below.

9 Gen Z Outfit Ideas to Recreate in Summer 2026

1. Hailey Bieber

Style Notes: Whether she’s selling Rhode for a billion dollars or dictating the season's biggest shoe trends, you’ll be hard pressed to find a celebrity Gen-Z adore more than Hailey Bieber. With a style that toes the line between pared-back minimalism and fashion-forward It girl, everything from floral appliqué dresses to capris and pointelle tees feature in Hailey's summer outfit rotation. And the shoes? Think classic. Regularly seen in The Row City flip flops, their streamlined shape is the perfect finishing touch.

2. Iris Law

Style Notes: As the quintessential London It Girl, Iris Law’s summer outfits have become the stuff of legend. Blending unexpected textures with eclectic prints, and kitschy accessories with the coolest hybrid shoes on the market, her bold summer outfits feel innately Iris in all the best ways. Whether she's pairing a pinstriped mini skirt 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.

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 Charli XCX’s star-studded 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 adore it. Her recent look in Rome in a gingham skirt, peep-toe and 3/4 length t-shirt is so charming, it's one you're likely to see replicated this summer.

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-Zer’s lips. On the press tour for her latest album, the ex-London resident channelled her innermost 2000's 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.

5. Alex Consani

Style Notes: 2024's 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, its her recent balloon trousers, loose shirt, and peep-toe heel combination during a Parisian excursion that I’m looking to recreate ASAP.

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 last couple of years, the ex-Disney star is proving to be one of pop culture’s most compelling recent style icons. Expect drop-waists, mini dresses, tall heels and lots of sparkle in her tour wardrobe, but well-deserved downtime in t-shirts, loose jeans and ballet flats.

7. Billie Eilish

Style Notes: If you don't subscribe to the "anti-trend" rhetoric, Billie Eilish’s summer style might not be for you. However, we at Who What Wear UK think it's high time to give the singer her flowers for being unapologetically herself. With layered tees and oversized silhouettes becoming Billie brand signature, at her press junket for the Billie Eilish: Hit Me Hard and Soft -The Tour movie, Billie's look feels decidedly fresh. Be it the divisive, witchy Prada pumps or the knee-grazing pleated skirt with stockings, it's a look I can already see in cinemas recreated 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 for the perfect pout). Having now evolved out of her skinny jeans and logo-mania ways, today her summer style is all about body-con 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.
