Charli XCX’s Brat album, released in June 2024, sparked more than just music—it ignited a cultural revival known as Brat Summer, rooted in early 2000s indie-sleaze fashion and neon green aesthetics. Though Charli recently declared the era “officially over,” the revival lives on in 2025, fueled by fashion drops, tour visuals, festival appearances, and TikTok trends.
Brat Summer is about unapologetic self-expression—messy hair, unfiltered confidence, and a pinch of chaos. It embraces gritty Y2K-style with lime-green accents, Von Dutch trucker hats, hot pants, ripped tights, and smudged smoky eyes . As The Tufts Daily described, it “brings back early 2000s indie sleaze to the pop landscape” .
A few key reasons explain why Brat style is resurfacing now:
- Brat Tour keeps it alive
Charli’s Brat Tour extends into 2025, showcasing iconic neon-green visuals and stage designs . - Festivals like Primavera
She headlined festivals (e.g., Primavera Sound Barcelona) in 2025, reviving energy and aesthetic for fans. - Fashion evolution
High fashion and streetwear are embracing Y2K nostalgia with neon tones, leather, and edgy styles . - TikTok momentum
The Brat aesthetic continues to trend, with creators reinterpreting it in new ways.
- Tour Wardrobe & Stage Art
Shows across North America feature neon staging and gift Brat swag—keeping the energy alive through visuals . - Festival Presence
At Primavera, Charli XCX delivered classic Brat songs (365, Apple), reminding fans why the aesthetic still matters. - High-Fashion Collaboration
Luxury and fast fashion alike are reissuing tracksuits, silos, and neon accessories nodding to the Brat aesthetic . - Social Media Trend Revival
TikTok creators remix the look; brat green accessories, early-2000s visuals, and messy glam makeup stay in rotation.
- Authentic rebellion: Rejecting the polished “clean girl” look in favour of raw, imperfect styles .
- Y2K nostalgia: Riding the wave of Y2K revival, but with an edgier, messier twist .
- Cultural simultaneously: With high-fashion adoption and grassroots styling, Brat Summer straddles pop culture and underground edge.
Charli has hinted at a transition to “Celine Song Summer” in 2025—shifting toward emotional nuance and romance—but the Brat green vibe remains influential. The aesthetic may morph into fall or winter versions, as remix albums keep the spirit alive .
Expect neon threads, early-2000s grit, and messy glam to stick around—influencing fashion, music visuals, and social media trends well into 2026.
Brat Summer may have peaked in 2024, but its spirit is far from gone. Whether replaying tour anthems, unboxing neon merch, or scrolling TikTok recreations, Charli XCX’s aesthetic echoes through 2025. It’s messy, confident, and unapologetically bold—a style that values raw energy over perfection.
If you want to capture the look:
- Think neon accents (especially brat green)
- Embrace Y2K layers and slightly unkempt vibes
- Mix party textures with everyday basics
- Let the attitude shine through
Brat Summer isn’t just a trend—it’s a cultural moment, and right now, it’s back on repeat.
