It's been a *very* fashionable few days for Sydney Sweeney, who has finally embarked on the press tour for her upcoming, much-hyped rom-com film Anyone But You alongside co-star Glen Powell – and she's pulled out alllllllll the stops for the occasion.

We're seriously not exaggerating. Thought her see-through gown covered in crystal icicles for the film's New York premiere a few days ago was as good as it gets? Not even close, ppl. For in the past day alone, the 26-year-old Euphoria star has given us the gift of not one, not two, but FIVE stunning outfits as she makes her way around town promoting the film – and it literally feels like Christmas has come early here on the Cosmo fashion desk.

Sydney's epic style marathon started off with a cute lil ode to Barbiecore, which is clearly far from over if her head-to-toe powder pink Versace ensemble is anything to go by...

Consisting of a mini shift dress with belt detail, matching coat, co-ordinating pink bag and heels, and statement white sunnies, this look is giving Sixties housewife-meets-First Lady, and we absolutely love it. But that's just the start...

To hit up the Upper West Side later in the day, Sydney switched to a contrasting all-black look that's a sexy twist on business dressing by Philosophy di Lorenzo Serafini. The cut-out top and collar details are just genius, we think.

Buuuut that look didn't stay on for long either, as next thing we knew, Sydney was out and about again in an *incredible* super-pale-grey sequin-covered waistcoat and matching trousers by ultra-luxe Italian brand Brunello Cucinelli, paired with Miu Miu accessories. Bellissima!

Everyone's clicking on...

And for the evening events? Sydney nailed it once again in a forest-green structured mini-dress that she wore with an oversized black coat, sheer tights and classic heels – before changing one final time for her most memorable look of the lot...

Yup, channeling a modern-day pin-up, Sydney rounded off her big fashionable day out with an appearance on The Tonight Show with Jimmy Fallon, wearing a custom Balmain mini dress in the shade of the moment: bright tomato red. The corseted bodice! The bang-on-trend corsage! The structured cups! The cute lil sleeves! The 80s prom aesthetic of it all! Absolutely glorious.

Oof! We're exhausted just writing about it, so can only imagine how ded Syd must be from all the endless serving. Hats off to her!
