Channelling her inner bride, Snezana wore a breathtaking white floor-length gown, which featured a beaded top and silk skirt by Australian designer Pallas Couture.
Personal trainer Sam looked dapper as can be in a chequered blazer, a crisp white shirt, skinny tie and black trousers.
But it was the couples’ beaming smiles that was their best accessory as they mingled with friends and family under twinkling fairy lights on Melbourne’s trendy Pop Up Patch rooftop.
Taking to Instagram, the Perth-born beauty thanked her loved ones for a memorable evening.
“Dream engagement party with my dream man in this Dream Dress!,” Snez penned.
While Sam added: “Arriving at our engagement party last night. Snez looking breathtaking. What a memorable night with our families and friends.”
The molecular genetics and biotechnology graduate also shared a precious snap with her ten-year-old daughter Eve, who looked gorgeous in a pastel pink layered tulle dress.
“My little fairy princess,” the mother-of-one beamed.
But the weekend wasn’t all smooth sailing with Snez being accused of photoshopping a social media shot of her toned tum.
The controversy erupted when she uploaded a close-up shot of her washboard abs, revealing her new-found physique is all thanks to fiancé Sam’s new fitness program.
“So damn glad I did the @samjameswood 28×28 workouts in Feb to make sure my dress for our engagement party last night looked incredible on,” she explained.
One user, who has since deleted their comment, accused the Bachelor season three star of doctoring the image.
“Explain how you photoshop a body? Either way thank you means my body looks rocking and to [sic] good to be true clearly the 28×28 work outs are working,” Snez quickly replied.
The jibe is probably the least of the star’s worries as 2016 is shaping up to be her best year yet! In January, she and Sam purchased their first house together in Melbourne’s Elsternwick – a three-bedroom property for a cool $1.65 million.
And the couple are hoping to fill up that spare bedroom as soon as possible with Sam revealing they want to start a family very soon. “It’s not if, it’s when,” the 35-year-old recently confessed.
