The 15 key trends of summer 25

The most stylish of summer 2025? It’s you! We’ve spotted 15 must-have fashion trends for you that are as cool as they are easy to wear. Leopard print, romantic ruffles, T-shirts with a committed message, chic wicker baskets, shirt dresses, and much more… Find among our designers the key pieces of the season to adopt and mix with the fashion essentials you already have in your wardrobe. Good news: you probably already own (at least) half of them! Summer is yours!

A message t-shirt

What’s cooler to spice up a look than a T-shirt with a heartfelt message? A truly stylish all-purpose piece, it adds an instant dose of coolness to any outfit. All it takes is a clever slogan to transform a pair of sensible office pants into a faux-serious look, or to twist basic jeans into a fashion statement. The message T-shirt is a bit like our cotton Proust madeleine: regressive, but incredibly trendy.
Our advice? Dare to go for a bittersweet message and wry humor with R13 designs, for a rock ‘n’ roll twist that’s sure to spice things up. Because sometimes, it’s the T-shirt that does the talking for you… and it does it with style and wit.

Ruffles

Ready, set, fly… ruffles! This season again, in keeping with the bohemian chic trend, ruffles are firmly at the top of the fashion podium. Romantic, airy, and ultra-feminine, they infuse our summer looks with an irresistible dose of lightness and movement. On a flowing blouse, a bohemian dress, or even gypsy-style shorts, ruffles dance with every step and reflect our desire for freedom and style. A true ode to modern femininity, they combine casual elegance with a sunny summer.
Our advice? Dare to layer or wear statement pieces with ruffles for a guaranteed wow effect. This summer, let your style shine with pieces that have volume… and character!

Tailoring

Give your summer character and charisma with one of the season’s major trends: revisited tailoring. Inspired by the menswear wardrobe, women’s tailoring brings a breath of chic structure to our summer silhouettes. The idea? Take on the codes of the classic suit to create looks that are elegant, modern, and assertive. Say goodbye to rigidity and keep only the best: a perfectly cut blazer jacket with an impeccable drape, effortlessly paired with fashion basics. High-waisted jeans, a minimalist white T-shirt, feminine boots, or heeled sandals: the blazer adapts to every mood, from office looks to casual chic.
Our advice? Adopt a summer power dressing, combining chic looks with controlled casualness.

A micro-short

Get your legs ready, because this summer, the trend is getting bigger with the comeback of micro shorts! Ultra feminine, deliciously sexy, and decidedly daring, micro shorts are the star piece for sunny days. Short but always stylish, they adapt to any situation, as long as you accessorize them well! A must-have for summer 2025, micro shorts mark the return of absolute glam. Adopt them now, without moderation.
Our advice? For an urban version, opt for an oversized shirt, a structured blazer, and beautiful sandals for a look that’s both sharp and balanced. For a beachside or festival look, a lingerie-style top, a bikini top, or a lightweight crop top will do the trick!

Wide jeans

This season, set sail… and in style! No need to choose between comfort and style; both go hand in hand with the new wide-leg jeans trend. High-waisted, loose-fitting, and soft denim: these generously sized jeans promise a relaxed, yet ultra-stylish look. Perfect for a casual-chic silhouette, they flatter all body types by elongating the leg while emphasizing the waist. Absolute comfort, bold style, and a denim attitude: wide-leg jeans are a must-have for this season’s wardrobe!
Our advice? Wide-leg jeans are a true everyday fashion ally. They’re easy to pair with a fitted top or a minimalist white T-shirt to play with contrasting volumes and create a balanced, modern silhouette.

Slim jeans

Calling all stylish nostalgics: slim jeans are making a comeback! Following in the footsteps of the “indie sleaze” trend, this 2000s revival blended sexy grunge with a laid-back look. Yes, women’s slim jeans are making a comeback in our wardrobes with panache. A true sculpting piece, slim jeans are the ultimate flattering pair. Their high waist and close-fitting cut highlight curves, elongate legs, and elegantly accentuate the silhouette. They’re the perfect blend of confident femininity and an effortless look. Their greatest asset? They go with everything. From timeless basics to seasonal statement pieces, slim jeans remain a must-have in any woman’s wardrobe, ready to follow you everywhere, all summer long and beyond.
Our advice? Adapt them to suit your every mood: a romantic blouse for a bohemian chic feel, an oversized shirt for a modern contrast, or a leather biker jacket to awaken your rocker side. During the day with trendy sneakers or ankle boots, or in the evening with pumps, slim jeans suit all styles and all body shapes.

The leopard print

Can we still call leopard print a trend? More than a pattern, it’s a timeless classic, an iconic print that transcends the seasons without ever losing its appeal. Whether in summer or winter, in subtle touches or as a bold total look, leopard remains a sure bet in the fashion wardrobe. Reinterpreted in a pop version with flashy colors, or enhanced with raw denim, it adapts to all styles: rock, bohemian, or urban. We love it on a flowing dress, a structured blazer, or even fierce jeans! Leopard print is the art of making your look roar with elegance. It flatters all body shapes, enhances all skin tones, and appeals to all generations. It’s wild, chic, sexy, and timeless.
Our advice? Leopard print isn’t just a trend. It’s a fashion staple, a wardrobe essential. Find YOUR favorite leopard print and wear it without moderation. Because this season again (and for a long time), we’re shouting it loud and clear: long live leopard print!

Flowers

Changing souls, changing hearts… with bouquets of flowers? What if fashion got in on the act too? This season, floral prints are making a flamboyant comeback in our wardrobes, carried by a bucolic and poetic wave that breathes a breath of fresh air and freedom into our silhouettes. But be warned, there’s no question of sentimentality here. What we love more than anything are flowers with a strong personality: graphic, rock, rebellious, far from overly prim or romantic clichés. Perfect for creating urban, modern, and bold looks, they add the touch of floral character we’ve been missing.
Our advice? Ditch the classic floral dress, which can sometimes be too literal, and instead opt for a strong, offbeat piece, like these slightly ripped floral print jeans by R13. The perfect balance between femininity, grunge vibes, and a nonchalant attitude.

Pastel pink

Who said pastel pink was just for bubble gum or little girls? Say goodbye to clichés from another era! In 2025, pastel pink is establishing itself as an ultra-trendy, modern, and incredibly desirable color. Soft but never bland, it brightens the complexion and injects a touch of pop freshness into any look. It pairs beautifully with denim, crisp white, or even touches of black leather for a more rock look. In short, it’s the must-have pastel shade of the season, to be embraced without moderation!
Our advice? Opt for an easy piece, like this quirky slogan T-shirt by R13, a casual-chic wardrobe essential. Wear it with high-waisted jeans, a flowing skirt, or under an oversized jacket, whether in the city, on weekends, or on vacation. This summer, see life in pink… but in a cool and contemporary version!

A basket

An absolute summer icon, the basket returns every year to weave its magic into our wardrobes. Immortalized on the arms of Jane Birkin or Brigitte Bardot, this wicker bag has become much more than a beach accessory: it’s the ultimate bohemian chic it-bag. Good news: no need to have reserved a deckchair to succumb to its charm! In 2025, the rattan, raffia, or woven straw basket can be worn everywhere, all the time, and with everything. In mini or maxi versions, with short or long handles, embroidered or raw: it effortlessly replaces the leather bag and stands out as the finishing touch to a casual chic, romantic, or ultra-trendy look. A key summer accessory, the basket is no longer just a market or beach companion: it’s a true fashion statement, a summer wardrobe essential that flirts between tradition and modernity.
Our advice? For a successful fashion look, pair your basket with a printed dress or a high-waisted jeans and white t-shirt set to reinforce that urban bohemian style that we love so much.

Boho chic

Add a touch of escape and authenticity to your looks by embracing the boho chic trend! Inspired by nomadic looks, bohemian style, and the free spirit of the great outdoors, this iconic fashion trend is back in force this season, bringing a warm, wild, and stylish breeze to our silhouettes. On the menu: warm colors, natural materials like linen, raw cotton, or suede leather, artisanal details, and of course… fringes for movement and character. We love this mix of bohemian comfort, ethnic elegance, and adventurous allure that gives each outfit an extra touch of soul. To embrace the trend right away, opt for the “Paco” fringed bag by Jérôme Dreyfuss, a true centerpiece of the boho chic wardrobe. With its soft leather, its design inspired by modern adventurers, and its fringes, it embodies the spirit of the trend: free, stylish, and assertive.
Our advice? Wear it with a flowing maxi dress or denim shorts and a sleeveless top for a look that’s as strong as it is timeless.

Marine style

Ahoy, sailor! The nautical style is making a comeback, sweeping spring-summer fashion like a wave of freshness. Timeless, elegant, and incredibly stylish, the sailor look, or navy style, is a must-have for any summer wardrobe. Inspired by the nautical world and seaside wardrobe, this iconic style plays with blue and white stripes, structured cuts, and gold or anchor details. The good news is that it suits all body types and all occasions, whether as a subtle touch or a bold total look. We’re focusing on nautical essentials like a classic long-sleeved striped top for cool evenings, a short-sleeved version for sunny days, and wide-legged white pants for a chic and relaxed look. Wear with elegant sandals or even sneakers for a modern and effortless silhouette.
Our advice? Accessorize with a basket to complete this look that exudes French summer chic.

The tiles

An iconic 90s wardrobe motif, checks are making a remarkable comeback this season and are a true fashion statement. The shirt, a true statement piece, can be worn open over a graphic tee, tied at the waist in 90s style, or closed and tucked into your favorite jeans! As for pairings, mix checks with raw denim, an oversized blazer, or a leather biker jacket for an ultra-trendy rock effect.
Our advice? Make checks your new staple, to wear both in the city and on weekends, for a style that blends grunge influences, a 90s revival, and casual elegance. This summer, one thing is certain: checks are in, but always with style!

The stripes

Timeless, elegant, and always on trend, stripes set a fashion trend that’s sure to be followed. This summer, it’s impossible to ignore this graphic print, which is chic, structured, and universally flattering. In vertical stripes, they elongate the silhouette, refine the figure, and add a real dose of minimalist sophistication. We love them on an oversized shirt for an ultra-stylish boyish effect, on an arty shirt for an edgy vibe, or even on creative pants, perfect for creating a fashionable and confident look. This season, stripes are setting the tone. Follow them!
Our advice? Mix them with solid pieces to balance the volume, or play with bold layering by pairing them with other patterns (checks, florals, polka dots) for a bold mix-and-match look.
