Jules shared her own post featuring herself and Guy in their finery on Instagram.
"What a night! #apras is an incredible celebration of musicians and songwriters who bring us the joy of music. So lovely to be in a room full of such talented humans and the people who make it happen behind the scenes," she captioned the snap taken in their Sydney home.
But it was Jules' fashion-forward look that had fans talking.
"That suit is 🔥🔥🔥🔥🔥," exclaimed singer Ricki-Lee Coulter.
"The fash is on fleek gal!" another person penned.
"Looking absolutely fabulous @julessebastian ❤️❤️❤️," remarked a third.
The stylish mum-of-two also shared an up-close look at her shimmering suit on her Instagram Stories and made sure to show off the diamond-style detailing.
"Check out this suit! Thank you very much Sass and Bide, killing it," she said.
"Very rock and roll."
Whether you're wanting to make an entrance at work or have a glam event to go to, power suits are making a comeback. That's right, it's not just an eighties wardrobe item anymore.
This sequined ensemble from Pretty Little Thing comes in black and gold and is the ultimate Saturday night party outfit.
For something a little brighter, the Little Mistress tailored sequin wrap blazer in black co ord will make you shimmer and shine a la Jules.
Or if black and sequins isn't your vibe, why not go for something with a statement pop of colour?
