The socialite poses for the bridal publication's June/July issue, which goes on sale May 6, looking positively gorgeous in chic designer wedding dresses.
She models an array of feminine silhouettes including a strapless column gown with a sweetheart neckline to a frothy confection with an elaborate full skirt.
We scored an exclusive sneak peek of the photo shoot, and it goes without saying that the fashionista stunned in each ensemble, increasing our curiosity ever more as to what she'll ultimately wear when she walks down the aisle.
Palermo offered several smart styling tips for brides-to-be who aspire to dress like her.
"Check out the Marchesa, Oscar de la Renta, or Carolina Herrera shows online. And even if your dream dress comes right off the rack, add your own touch. Play with color. It's all about the styling!" she said.
Olivia also confided that she'll be doing just that on her wedding day.
"I always like to incorporate pops of color," she hinted.
As for her sweet romance, Palermo was positively brimming with happiness when asked about their love story.
"Friends set us up, and it just fell right into place. We're a great team. We understand and respect each other, and we make each other better people. It also helps that we both work in fashion and can travel the world together. We get to see the world through each other's eyes," she told the magazine.
Sounds like a match made in heaven.
