Pia's structured top and fringed skirt were paired with classic pointed-toe black pumps, a black Sarah J Curtis Collection wide-brimmed hat, hoop earrings, a single cuff and her stunning new engagement ring from her boyfriend, Tyson Mullane.
The pair held hands as they strolled through the G.H. Mumm Marquee, marking their first public appearance as a betrothed couple.
How sweet! Pia and Tyson shared their happy news over the weekend, with heartfelt Instagram posts about the big proposal day.
"In a hundred lifetimes. In a hundred worlds. In any version of reality. I’d find you & I’d choose you. Yes today. Yes always," Pia captioned this gorgeous photo.
