The TV personality, 32, who landed a huge job on the US version of Love Island, ditched her bra in the figure-hugging outfit.
The Irish beauty flashed a big smile as she posed for a selfie in her dressing room.
Maura, who shot to fame on the 2019 series of Love Island UK, shared a series of snaps on Instagram, showing off her toned figure in the backless dress.
She wore her brunette tresses in a loose plait and wore flawless bronzed make-up.
The TV star accessorised her look with silver hoop earrings and a pair of beige cowboy boots.
Maura has taken over Love Island USA’s social channels but it seems she’s making the most of her downtime in paradise.
She recently showed off her enviable figure in the blue bikini top and matching thong bottoms.
Since leaving the villa in 2019, Maura has hosted segments on This Morning and fronted the BBC’s show Glow Up Ireland.
And Love Island USA recently announced the news that she was joining the team, writing: “This just in…Maura Higgins will be your social ambassador this season bringing (sneaking) you the BTS scoop all summer!”
The news went down very well with fans, with one writing: “@maurahiggins is my all time fave love island girl! Having her on 🇺🇸 is epic!”
A second said: “A LOVE ISLAND LEGEND!!!!!! Welcome to Love Island USA Maura Higgins.”
