Christian Siriano has big designs on marriage.
The Project Runway champ is engaged to his longtime boyfriend, musician Brad Walsh.
The designer revealed the ecstatic news Sunday on Twitter, posting a photo showing their snazzy engagement bling: matching bracelets.
"Yesterday @BradWalsh and I exchanged engagement bracelets!" the 27-year-old Siriano wrote.
Walsh himself later took to Twitter to share the news.
"We've told our moms so now we can tell you. Yesterday we exchanged engagement bracelets," he wrote.
In 2008, Siriano won the fourth season of Project Runway and has since gone on to a booming career as a designer, dressing the likes of Christina Hendricks and, of course, Runway maven Heidi Klum.
Last year, Siriano and Walsh proudly showed off their sleek apartment in Manhattan's Chelsea neighborhood, where they've lived since 2010. The place has since become an exhibition space of sorts for Siriano's burgeoning love of antiques.
"Christian started getting much more into antique and vintage finds," Walsh told lifestyle blog The Byrne Notice. "So the new space sort of became the canvas for that, and slowly the modern furniture was phased to the office or out of the picture entirely."
The duo are also great collaborators on the runway: Walsh has created the music for Siriano's shows, and he most recently provided the beats for his fiancé's 2013 fall/winter presentation.
Congrats to the happy couple!
