Rumer Willis looked ethereal in a flowing white dress as she posed under an azure sky while vacationing in Greece.

The 32-year-old actress shared a stunning image to Instagram on Sunday that featured her standing in a ray of sunlight against the rugged desert backdrop.

The Once Upon A Time In Hollywood star donned Doen's ruffled semi-sheer Ischia dress for her dramatic selfie.

The dress boasted double puffed sleeves and a drawstring waist. A glimpse of the the hot pink and blue patterned bikini top that Rumer wore under the dress could be seen through the delicate fabric.

Willis sported a pair of edgy cat-eye sunglasses by Australian eyewear brand Oscar and Frank. She accessorized with gold Jacquie Aiche fishtail earrings. 

The brunette beauty's hair was parted and pulled back from her face as she gazed into the camera. Rumer captioned the post simply with a desert emoji. 

On Friday, Willis hit back at 'haters' leaving unkind comments on a recent Instagram post. After slipping into a skimpy yellow and orange thong bikini, the Hostage actress showcased her peachy bottom in a photo with the caption: 'For the haters…. With love and gratitude kindly my [peach emoji]. I'll keep smiling regardless.' 

Just hours before, Rumer - who is in Greece with her mum Demi Moore and her two younger sisters Tallulah and Scout Willis - shared a sultry snap of herself in a green bikini with pink sunglasses.

While much of the feedback was positive, not everyone was as kind in the comment section below Rumer's snap.

'Nope,' one social media user bluntly wrote.

'Yikes, not appropriate,' added another, with a third saying: 'Why does everyone in Hollywood need to pose like this. It's like they need to say look at me, I'm wonderful.'
