Brat Summer

The 2024 Pop-Cultural Aesthetic-Substantive Cycle

Also known as: Brat · Brat Aesthetic · Lime-Green Summer · Charli XCX Brat · It's Brat

Brat Summer is the four-month cultural cycle that crystallized around Charli XCX's Brat album (released June 7, 2024 on Atlantic Records) and produced sustained visibility across pop music, fashion, brand marketing, and US presidential politics. The album's lime-green cover (a deliberately ugly 8-ball-evoking yellow-green chosen by designer Brent David Freaney) became the cycle's signature visual; the album's "club rats taking themselves seriously" emotional register became its signature mood. Kamala Harris's presidential campaign appropriated the framing on July 21, 2024 — within hours of Joe Biden's withdrawal from the race — when the Charli XCX X account posted "kamala IS brat," and the Harris HQ account changed its profile banner to lime-green. The cycle peaked across July-August 2024, extended through Charli XCX's October 11, 2024 Brat and It's Completely Different but Also Still Brat remix album, and softened by November 2024. The strategic point for brands is that Brat Summer is one of the cleanest contemporary case studies of cultural-cycle absorption into both commercial and political marketing — showing what's possible when timing and authenticity align, and what fails when brands arrive late.

The intellectual lineage runs through Charli XCX's career. Charlotte Aitchison began posting music online in the late 2000s; her 2014 collaboration with Iggy Azalea ("Fancy") and 2017 mixtape Pop 2 established her as a hyperpop-coded pop artist working with producers including A. G. Cook and SOPHIE. Brat was her sixth studio album and first to reach commercial scale outside the hyperpop-and-pop-critic audience that had been following her for over a decade. The cycle's brand-marketing absorption tracks through standard contemporary microtrend journalism — Rebecca Jennings at Vox, Joe Coscarelli at NYT, Vanity Fair, The Atlantic, Vogue — and the political-marketing dimension was unprecedented in 21st-century US presidential campaigns. Jia Tolentino's Trick Mirror (2019) and Kyle Chayka's Filterworld (2024) provide the broader cultural-criticism frame for thinking about how contemporary cycles like this operate.

How it works

Brat Summer operates on three structural moves that distinguish it from most 2024 microtrends.

Cross-domain absorption. Most cultural cycles run through one or two domains (fashion, music, brand marketing). Brat Summer ran through music (the album), fashion (lime-green visual cycling), brand marketing (Hellmann's, Volkswagen, Mountain Dew, etc.), AND US presidential politics (the Harris campaign). The cross-domain reach is unusual and partly explains the cycle's four-month duration versus the typical six-to-eight-week microtrend window.

Politically-attached cycle. The Harris campaign's July 21, 2024 absorption of "brat" framing — within hours of Biden withdrawing from the race — was a structurally novel moment in US political marketing. Presidential campaigns typically don't move that fast on cultural cycles, and the speed produced both significant initial benefit (free media, rapid creator-economy alignment) and subsequent risk (the framing aged with the cycle, which complicated November positioning).

Authentic-creator-direct anchor. Charli XCX herself participated continuously through the cycle — the album, social-media engagement, the October remix album, sustained performances. Brand-marketing absorption that aligned with her direct activity worked; brand uses that ignored her direct presence read as appropriation.

A 2026 wrinkle: Brat Summer is now a teaching case in brand-marketing pedagogy for what does and doesn't work in compressed-cycle engagement. The Harris campaign's success and subsequent November loss complicate the analysis — political consultants and brand-marketing analysts disagree about how much credit/blame the brat-coded positioning deserves for either outcome.

Variants

Album-and-music variant

The originating cultural product. Brat reached approximately 165K first-week album-equivalent units in the US , peaked at #3 on the Billboard 200, and produced sustained streaming numbers across summer-fall 2024. The October 11, 2024 remix album Brat and It's Completely Different but Also Still Brat extended the cycle through collaborations with Lorde, Billie Eilish, Ariana Grande, and others. Charli XCX's June 2025 Brat tour extended commercial relevance into 2025.

Lime-green visual cycle

The most-imitated brand-marketing surface. Hellmann's ran lime-green mayonnaise positioning ("Mayonez Era"); Volkswagen ran lime-green Beetle imagery; Mountain Dew, Crocs, and a wave of CPG operators ran lime-green-coded social copy. The Pantone 376 C-adjacent color became the cycle's signature.

Kamala Harris political campaign

The cycle's structurally-novel political absorption. Within hours of Biden's July 21, 2024 withdrawal, Charli XCX posted "kamala IS brat," and the Harris HQ profile shifted to lime-green. The campaign's subsequent uses of brat-coded framing extended into August-September 2024 (with notable adjustments after Tim Walz's selection as VP nominee shifted the campaign's broader cultural framing). Whether the brat positioning helped or hurt the Harris campaign is contested.

Brand-Brat-tweet wave

The standard brand-marketing absorption wave. Most major CPG brands ran some form of brat-coded social copy during July-August 2024. Most produced moderate engagement followed by saturation. By September the cycle had over-saturated and brand uses began producing diminishing returns.

Hyperpop-subculture context

The originating subcultural context. Charli XCX's career sat inside hyperpop and adjacent experimental-pop subcultures (100 gecs, A. G. Cook's PC Music label, SOPHIE's broader influence) for over a decade before Brat. The variant matters because it explains why the Brat breakthrough produced the cycle's specific aesthetic vocabulary — the lime-green-and-club-rat sensibility was already developed inside the subculture before reaching mainstream visibility.

When it breaks

The primary failure is late brand entry. Most brand-marketing operations arrived in the cycle in late August or September 2024, after audiences had already absorbed the framing. Late entries produced diminishing engagement and sometimes outright cringe-coded reception.

The second is misappropriation of the political dimension. Some brand uses of "kamala IS brat" framing without recognizing the political content read badly. The cycle's defended boundary became more politically charged after the Harris campaign appropriation.

The third is cycle-fatigue conversion. By October 2024, brand-Brat-coded content had saturated past audience tolerance. Brands continuing to deploy the framing in October-November 2024 were operating against a cycle that had already exhausted itself.

The most expensive failure is strategic-position lock-in to a politically-charged cycle. Brands whose brat-coded positioning got read alongside the Harris campaign's framing carry exposure regardless of which side of US politics they're on. The structural lesson is that brand-marketing engagement with politically-coded cultural cycles produces durable association that survives the cycle.

In the wild

Played straight. A brand engages directly with Charli XCX or her ecosystem during cycle peak. Few brands executed this well; most who tried arrived late.

Inverted. A brand explicitly stays out of the cycle. Default for most luxury and heritage brands.

Subverted. A brand engages Brat Summer dynamics while commenting on them — work that addresses the brand-saturation problem directly. Rare.

Averted. A brand declines the cycle entirely. Default for most B2B and infrastructure operations.

Canonical examples

Charli XCX, Brat (Atlantic Records, June 7, 2024)

The originating album. Brat was Charli XCX's sixth studio album, produced primarily with A. G. Cook with additional production from George Daniel and others. The album's deliberately-ugly lime-green cover (designed by Brent David Freaney, with Helvetica Bold lowercase typography) became the cycle's signature visual. The album reached approximately 165K first-week album-equivalent units in the US, peaked at #3 on the Billboard 200, and crossed 1B Spotify streams within roughly four months . Canonical case of pop album becoming cultural-cycle anchor across summer 2024.

Kamala Harris campaign brat appropriation (July 21, 2024 onward)

Within hours of Joe Biden's July 21, 2024 withdrawal from the presidential race, Charli XCX posted "kamala IS brat" on X. The Harris HQ X account responded with a lime-green profile banner. The framing extended through subsequent campaign communications across August-September 2024. The case is structurally novel because presidential campaigns typically don't move at that speed on cultural cycles, and the campaign's absorption of the framing produced significant initial momentum. Whether the positioning ultimately helped or hurt the Harris November campaign outcome is contested. Canonical case of political campaign absorbing cultural cycle in real time.

Hellmann's "Mayonez Era" Brat campaign (July 2024)

Unilever's Hellmann's brand ran a lime-green-Mayo positioning in July 2024 that became one of the most-cited brand-marketing brat absorptions. The campaign worked partly because Hellmann's social-media voice was already irreverent and partly because the brand entered the cycle relatively early. Canonical case of CPG brand engaging a microtrend at appropriate timing.

Volkswagen lime-green Beetle imagery (Summer 2024)

Volkswagen ran lime-green-Beetle imagery during cycle peak. The case is interesting because the Beetle had been discontinued in 2019, and the brand's use of legacy product imagery in service of a current cultural cycle showed how brand archives can be reactivated for cycle engagement. Canonical case of legacy-product imagery deployed in current cultural cycle.

Mountain Dew brat-tweet wave (Summer 2024)

PepsiCo's Mountain Dew ran sustained brat-coded social copy across July-August 2024. The campaign produced sustained engagement during cycle peak but also represented part of the brand-marketing herd that eventually saturated the cycle. Canonical case of late-cycle brand engagement that arrived in the saturation phase.

Charli XCX, Brat and It's Completely Different but Also Still Brat (October 11, 2024)

The remix album. Released approximately four months after the original, the remix album extended the cycle through collaborations with Lorde, Billie Eilish, Ariana Grande, Robyn, and others. The release strategy is structurally interesting — using a remix album to extend a cultural cycle by approximately three months, with each collaboration producing a discrete media moment. Canonical case of artist using remix-album strategy to extend cultural cycle commercially.

Vox Rebecca Jennings sustained Brat Summer coverage (June-October 2024)

Jennings's Vox coverage tracked the cycle in real time across multiple stories from June through October 2024. The coverage was unusually engaged on the cultural-and-political dimensions, including the Harris campaign appropriation specifically. Canonical case of microtrend journalism running synchronously with a major cultural-political moment.

NYT Joe Coscarelli sustained Brat Summer coverage (June-October 2024)

Coscarelli's NYT music-and-culture coverage tracked the cycle from a music-industry perspective. The pieces engaged Charli XCX's career arc, the album's production context, and the political absorption directly. Canonical case of mainstream-press music-criticism coverage that tracked the broader cultural significance rather than just the album as music product.

Brat Summer is one of the most-consequential cultural cycles of 2024 because of its cross-domain reach (music, fashion, brand marketing, presidential politics) and its political dimension. The Harris campaign's rapid appropriation produced both significant short-term momentum and durable cultural association — and how the broader brand-marketing ecosystem reads that association in 2025-2026 is still working out. The cycle's most durable strategic lessons are about timing (early entry rewards more than late) and authenticity (Charli XCX-direct alignment worked; ignorant appropriation failed). Brand-marketing operations adjacent to consumer-discretionary, political-adjacent, or pop-cultural categories should treat Brat Summer as a teaching case for what compressed-cycle engagement looks like at the upper bound of what's possible — and what the costs are when execution doesn't match the timing window.
