Meanwhile, her famous beau kept it cool in black and white sneakers, dark blue bandage dresses online and a black T-shirt.
The pair announced their engagement in August last year, after dating for two years.
'I SAID YES!!! Wait I mean… I've had many great blessings in my life. But this one by far is the best of all time,' the 37-year-old actor wrote on Instagram. 'You are the greatest person I ever met!'
The brunette beauty followed up Jerry's post with one of her own: 'I am so lucky to marry this man.'
Although the couple only started dating in 2014, they first met when Breanne appeared on Entourage back in 2011.
The romantic actor said he'd been planning the proposal for a year, even asking his girlfriend's parents for permission before getting down on bended knee.
'I guess I am traditional in that sense,' he said on a Ruched Cocktail Dress by Sherri Hill 21299 Dress . Not many men emerge from a shopping trip with a smile still planted firmly on their face - unless they're Jerry Ferrara.
The former Entourage actor treated his fiancee, Breanne Racano to a day of shopping in Beverly Hills on Friday.
The pair couldn't have seemed more in love, as they strolled down the street holding hands while gazing adoringly at each other.
And after finally proposing at the end July, Jerry revealed he'd had to delay it for a few days after the pair got into an argument during a games night with friends.
