Bikini or one-piece? Mega-shades or body jewellery? See what the stars are wearing poolside on their holidays this summer...
Summer may have only just started, but the celebs are already on their jolly holidays - so cue the most OTT, envy-inducing Instagram pics we'll see all year.
Taylor Swift, Rita Ora, Olivia Palermo and more are showing us a stronger beach style-game than ever, trialling as many trends as possible with statement one-pieces and colourful bikinis a-go-go.
From Kylie Jenner in her Baywatch-worthy Chanel one-piece, to Rosie Huntington-Whiteley's entire wardrobe of embellished bandeaus, the stars are out to show us that beachwear is about sooo much more than a boring black triangle top.
Millie Mackintosh, Charlotte Olympia and co. are also introducing us to cool new swimwear labels in their droves - hello Adriana Degreas's mermaid swimsuits and the genius Monday Swimwear. Because if you're wearing a bikini on a Monday, it's got to be a good day, hasn't it?
At the beach, by the pool, or just lounging on the decks of their super-yachts (we're looking at you Olivia P) the stars are literally making us weep at our desks with their Insta-postcards from paradise.
There are still some trends to note from last summer, too, from Rihanna's body jewellery, to Heidi Klum's crochet Kiini two piece, so get your beach style inspo from the best in this edit.
First up, it's Kourtney Kardashian, who worked not one, but three statement one-pieces on the beach in Miami. Our favourite? This studded one-shoulder number by Norma Kamali.

It really is a hard life for this stylish lot, isn't it?

Taylor Swift
Taylor Swift went on holiday with her then-boyfriend Calvin Harris earlier in the year, with Taylor posing up a storm in the tropics in some seriously hot colourblock bikini designs.
Millie Mackintosh
Millie introduces us to the Monday Swimwear brand. Because if it's Monday, and you're in a bikini, you must be having a good day.
Poppy Delevingne
Here's Poppy, making us all jealous as she gazes into the distance in Mustique.
Millie Mackintosh
Millie makes a case for the strappy suit, with this Agent Provocateur number.
Millie Mackintosh
Millie's cut-out white cossie by Calzedonia is stunning, but we'd worry about the grid-style tan lines!
Olivia Palermo
Olivia reminds us that the on-trend, off-shoulder top can make a stylish beach cover up, too.
Victoria and Harper Beckham
We can't even see the front of VB's swimsuit, but we suddenly know we need a berry-tone bikini in our holiday wardrobes.
Britney Spears
Britney's bod looks incredible in this canary yellow two piece.
Rita Ora
Here's Rita, posing up a storm in this sporty one-piece on her balcony in Miami.
Rosie Huntington-Whiteley
Rosie's halter top is super-flattering for smaller busts.
Charlotte Olympia
Charlotte Dellal is a mermaid. We're convinced by her Adriana Degreas sequin suit.
Charlotte Olympia
Tail shot, essential.
Taylor Swift
Here's Taylor Swift, working it somewhere tropical in a colour blocked solid style.

Heidi Klum takes on the IT bikini brand, Kiini, in all its rainbow crochet glory.
Rihanna
Rihanna reminds us that we can accessorise our classic bikinis with body jewellery, to give them a fresh trend look.

And here's Beyonce, coming out in praise of the super low cut one-piece.
Kendall Jenner
Kendall is into her chains, teamed with a classic triangle style by her pool in LA.
Jourdan Dunn
Bikinis should be show pieces, says Jourdan Dunn in this carnival-ready embellished number.
Elle Macpherson
Or they can be super-cool and low key, a la Elle McPherson who has teamed hers with a black crop top and a baseball cap.
