Chris Hemsworth channels the 1970s in Studio 54 fancy dress as Elsa Pataky goes underwear free

Retro! Chris Hemsworth channels the 1970s at Studio 54-themed fancy dress party – as Elsa Pataky goes underwear free in a sheer dress for the bash

Chris Hemsworth and Elsa Pataky set the bar high with their costumes at their Studio 54-themed New Year’s Eve fancy dress party in Byron Bay last week. 

After Elsa previously shared pictures going underwear free in a sheer dress at the bash, a picture of Chris’s eye-catching ensemble has now emerged.

Wearing flared trousers with a checkered design, a sleeveless shirt and retro sunglasses, the star looked like he’d stepped straight out of the 1970s.

The actor, 36, posed for a picture alongside wife Elsa and several friends, who had all dressed the part for the bash, centered around the New York City nightclub.

Elsa, 43, went underwear free in a sheer dress as she danced with friends and family – including Matt Damon’s wife, Luciana Barroso. 

Her glamorous frock featured intricate beading and white feathers at the hem. 

The mum-of-three also crimped her blonde hair extensions and accessorised with pineapple-shaped sunglasses.

Chris and Elsa hosted the party at their $20 million Byron Bay mega-mansion, which they finally moved into last month after a two year build. 

Elsa posed for photos on her mansion’s balcony with Luciana, as well as her mother-in-law, Leonie, and sister-in-law Samantha.

Samantha – who is married to Chris’ older brother, Luke Hemsworth – wore a black lace bodysuit, metallic shorts and silver boots. 

Leonie opted for a dazzling silver frock and styled her blonde hair loosely.

Elsa and Chris, 36, moved into their Byron Bay ‘mega mansion’ several weeks ago. 

The 4.2 hectare estate, which the couple purchased in 2014 for $7million, has been completely transformed and is now believed to be worth significantly more. 

In addition to a huge rooftop infinity pool, the property also boasts five bedrooms, 10 bathrooms and a butler’s pantry.

Perfect timing! The Hemsworth family moved in just before Christmas. Elsa is pictured here with her three children: daughter India Rose, seven, and twin sons Tristan and Sasha, five
