She does work in fashion after all!

For arguably the biggest style moment of her life — her wedding to Maroon 5 frontman Adam Levine — model Behati Prinsloo clearly couldn’t go with something off the rack. So of course, she turned to one of the most celebrated, celeb-loved fashion labels to help create her dream gown.

The Victoria’s Secret model went for a custom-made blush Marchesa gown — the result of a four-month collaboration with Georgina Chapman, who established the brand alongside Keren Craig.

“She was inspired by a runway dress from fall 2011,” a rep for Marchesa tells PEOPLE.

The inspiration gown (photo below) features romantic floral appliqués and a tulle train, but Prinsloo’s design had a sleeker silhouette with thin spaghetti straps made of silk and a low back. The bride capped off her look with a floor-length white silk tulle veil.

“She had final fittings a few weeks ago when she was in New York with Adam, while he was doing press for his film Begin Again,” a source tells PEOPLE.

With Levine preoccupied, Prinsloo “and Georgina were finishing the alterations,” the source added.

And her dress wasn’t the only thing customized for her big day. Prinsloo wore the same style Christian Louboutin “Valnina” shoes that hit the runway during the Marchesa spring 2014 show, which she had specifically made in white suede.

The model — who said her closet is filled with jeans, sundresses, vintage rock ‘n’ roll t-shirts and bikinis — has described her personal style as “more like hippie-bohemian.”
