Swedish actress Alicia Vikander shows off her trim abs in black bandeau bikini as she tops up her tan on beach in Ischia

Alicia Vikander looked incredible when she topped up the tan on the beach in Ischia on Sunday. 

The 26-year-old girlfriend of Michael Fassbender stepped out wearing a sexy black bandeau bikini which had a knot design at the cleavage and tie-sides on the briefs. 

The Ex Machina star is at the Ischia festival to accept the Breakout Actress Of The Year. The Global Film & Music Festival, which started last Saturday, is due to conclude on Sunday.

Swedish actress Alicia was already sporting a golden tan when she headed out into the sunshine and sprayed what looked like oil on her skin as she sat under an umbrella. 

She sat beside a glass of lemon water and a white pair of leather sandals, as she accessorized with a delicate gold bumblebee necklace. 

Tying her brunette locks in a relaxed up do, the rising star went make-up free for the occasion, letting her natural beauty shine through.

Get beach ready in Alicia's bandeau bikini top

There are certain wardrobe classics that everyone can appreciate, and a slimming black bikini is certainly one of them. Actress Alicia Vikander clearly rates the classics too as she holidayed in Ischia in a gorgeous bandeau style bikini top with tie detail to the centre.

The Ex-Machina star's strapless number is from the brand Eres and available to buy at Net-a-Porter (click to the right to purchase). It's sold as a set with a pair of basic black briefs, however Alicia's shown how to make it your own by creating a mix and match look with a different pair of tie side bottoms so you could easily pair this top with any style of black bikini bottoms.

Earlier in the week, Alicia was pictured catching up with Eliot Sumner, 24, of I Blame Coco fame - she is the daughter of Sting and Trudie Styler as they giggled in the sunshine. 

The pair have been friends for a while and were spotted chatting away in the front row of the Louis Vuitton show at Paris Fashion Week in March.

Alicia has just completed work on The Man From U.N.C.L.E. alongside Henry Cavill and Armie Hammer.

The movie is set in the early 1960s and CIA agent Napoleon Solo and KGB operative Illya Kuryakin participate in a joint mission against a mysterious criminal organization, which is working to proliferate nuclear weapons. 

Alicia recently told E! that director Guy Ritchie told her to slap co-star Armie in the face for a scene - and he had no idea about it. 

She told the site: 'Guy was like, "Go over there and slap him." I was like, "Can I?"' Adding: '[Armie] got a bit surprised the first time I did it. I was like, "I'm sorry."'
