While we're out here regretting every single second that we complained about last month's heatwave and praying that the sun finally returns, our fave celebs are already living their best summer holiday vibes in some of the most glamorous places on earth.

Kim Kardashian just posted some pics of herself in a cute lil blue thongkini on a gorge white sandy beach, Billie Eilish was spotted delightedly catching some rays by the pool at her friend's house, and practically half of Hollywood seems to have decamped to the glamorous French Riviera for some summer fun – we're talking Kendall Jenner, Hailey Bieber, Dua Lipa and our new fashion obsession Sofia Richie.

And the latest celeb to jet off on some seriously envy-inducing hols is none other than Euphoria star and all-round icon Sydney Sweeney. The 25-year-old actress swapped her Y2K-inspired outfits (we're still not over that baby pink cargo mini-skirt look) for the summer wardrobe of dreams as she spent a week with friends in Ibiza on one of the most insane yachts we've ever seen. Have a flick through her latest Instagram post to see what we're talking about...

Sydney can be seen rocking everything from a brown peep-hole slip and plunging pink mini-dress to a helmet and life jacket in her newest 'photo dump' – and naturally, looking insanely hot in every single outfit. But the look that's living in our minds rent-free? Her teeny, tiny black string bikini.

Scroll through to the sixth picture in the carousel if you haven't already, and you'll know what we mean. Sydney can be seen relaxing on the boat's deck in high-leg black bikini bottoms, a tiny matching top and a cute lil co-ordinating baseball cap to shield her face from the sun's harmful rays – all while munching on an orange ice lolly.

It's what we all want from our summer hols, tbh – and a reminder that sometimes when it comes to swimwear, the simplest is often the best. Forget bold prints, cutesy charms and complex silhouettes: the black micro bikini is a classic for a reason, and better for tan lines too.
