How Blake Lively turned an "Another Simple Favor" press tour look into a Gossip Girl homage, proving that once you’ve ruled the Met steps, every carpet is yours.

Yesterday in London, Blake Lively stepped out for the promo of her new film Another Simple Favor, slated for release on Prime Video on May 1st, wearing an outfit that made one thing very clear: Serena van der Woodsen may have graduated from Constance Billard, but her influence is still on the guest list. In what can only be described as a 2025 reprise of her Gossip Girl character’s all-girls private school uniform, Lively proved once again that she’s in control of the narrative, and just like Serena, always dressed for the part. This was no accident… Blake came to play. She leaned all the way into the reference, because Constance Billard never really leaves you — especially if Chanel is involved.

Let’s break it down: Blake’s look featured a black and cream Chanel cardigan with gold-button detailing, a leather miniskirt, sheer black tights, and slouchy, tall black boots. Add the oversized Chanel hair clip, glowy makeup, and megawatt smile, and you’ve got a grown-up Serena energy with just enough prep-school polish to make even Blair Waldorf clutch her pearls.

From a fashion PR perspective, it’s a genius move. Blake’s been under some scrutiny lately given the recent “It Ends With Us” lawsuits. And while there’s a lot of information circulating online, this outfit might be the loudest, chicest one she could’ve worn. By tapping into a pop culture persona the public already adores, Blake isn’t just giving us a look — she’s giving us comfort, familiarity, and something far more powerful than a public statement: nostalgia.

In public relations, nostalgia is strategy. It softens headlines, redirects attention, and reminds audiences what they liked about you in the first place. Here, Blake reintroduces herself not as a star caught in controversy, but as her Gossip Girl-era icon, Serena van der Woodsen, that we never stopped rooting for. It’s smart, it’s stylish, and it’s working.

The look is nearly a mirror image of the 2007 Constance-era Serena ‘fits that defined late aughts and early 2010s fashion for a generation of girls who believed the school hallway was the runway. Think loose ties, plaid minis, and undone Oxford shirts — the “I woke up like this, but glam” uniform that Gossip Girl practically copyrighted (thanks, Eric Daman!).

Side-by-side comparisons (they’re making the rounds, and I’m so here for it) show Blake now and Serena then, and the parallels are too perfect to ignore. From the mini-length skirt and leggy silhouette to the handbag sling and flirty waves, it’s giving “What if Gossip Girl graduated to global press tours?” energy in the best possible way.

Fashion-wise, it’s a masterclass in nostalgic dressing with a modern twist. The leather skirt and luxe knit elevate what could’ve been a costume into couture. It’s Serena grown up, not grown out. This is what happens when a fashion icon revisits her roots, without clinging to them, the way Blake Lively has perfected.

Isn’t that the point of all this? In a cultural era obsessed with Y2K redux and aesthetic reinvention, Blake’s look reminds us that the best way to nod to your past is to wear it like you own it… preferably with Chanel monogrammed buttons and killer boots.

So here’s to the legacy of the Constance Billard uniform. To undone ties and overdone drama. Honestly, it’s a uniform we’d proudly get detention for. And to Blake Lively, forever our Upper East Side “it” girl, rewriting the school dress code… one headline at a time.
