The American Snipper star - who is mother to four-year-old Marlowe - showcased her incredibly taut stomach in her skimpy multi-coloured crochet two-piece.

Her choice of swimwear exhibited her honed pins and peachy derriere as she strolled along the white sandy beach in her tie-side bikini bottoms that hung low on her hips.

While displaying her abs, she flaunted her decolletage in her plunging halterneck bikini top.

She covered her golden tresses in a large straw hat while working her locks into a side plait while navigating the beach wearing a pair of oversized sunnies and her beach tote over her shoulder.

Make waves like Sienna in a crochet bikini by Missoni

Sienna Miller is really on a roll right now when it comes to style.

She's been busy doing the rounds to promote her new movie The Lost City Of Z, wearing super high end labels like Sonia Rykiel, Chloé and Alexander McQueen. But even on laidback days on the beach she looks flawless!

Here she is taking a break in Mexico wearing a zig zag print bikini, which is by Missoni. We love the chic chevron crochet design (a Missoni signature) and classic triangle cut of this two-piece, which is also reversible. Talk about getting more for your money!

Sadly it has now sold out, but there's plenty more fish in the sea so click (right) to buy a similar current season bikini.

Or splash out on a similar style from our edit below. Topshop, River Island and Tori Praver have all got some Missoni-esque options to help you master the look.

Later, the fashionista enjoyed a dip in the Caribbean sea as she cold off in between her sunning sessions.

This time she left her locks loose as she jumped into the clear waters as her now slicked back tresses complemented her minimal beauty look. 

No doubt the trip to Mexico is a well-deserved one for Sienna, who has been busy as usual. 

The fashion darling is currently on the promotional trail for her new flick The Lost City of Z: A Tale Of Deadly Obsession alongside Charlie Hunnam and Robert Pattison.

Based on author David Grann’s 2009 book The Lost City Of Z: A Tale Of Deadly Obsession in the Amazon, the new film recounts enigmatic explorer Fawcett’s attempts to find an indigenous city in the wild, remote and largely unchartered South American jungle.

Fawcett (Hunnam) and his son would eventually vanish without trace in 1925, never to find their city. In the flick, Sienna plays the lead's wife Nina Fawcett.

Aside from promotional trails, the model-turned-actress will be starring in the upcoming thriller The Burning Woman opposite Christina Hendricks and Aaron Paul. 

Directed by Jake Scott, the film is about a woman who takes in her granddaughter following the disappearance of her own daughter.

Meanwhile, Sienna recently gushed about her ex Tom Sturridge - who she shares daughter Marlowe Ottoline Layng with. 

Despite their four year romance coming to an end in 2015, she described him as her 'best friend'.  

The actress, who shares four-year-old daughter Marlowe with Tom, told Harper's Bazaar: 'It's great for our daughter that she has two parents who love each other and are friends… He's definitely my best friend in the entire world.'
