Sarah Cummins had paid United States $30,000 (AUD $38,000) for the nonrefundable wedding reception for 170 people.
With a nonrefundable contract at the venue, the Ritz Charles in Carmel, Ind., and enough gourmet food for 170 guests who would no longer be attending, Cummins chose to invite dozens of homeless people to prevent the food from going to waste.
Cummins worked with the venue's event planner to rearrange the reception area, then contacted homeless shelters in Indianapolis and Noblesville, Indiana, to invite residents to the reception.
For Cummins, though, the kind gesture was a distraction from her heartache.
She told the Indianapolis Star that she and her fiance called off the wedding a week ago.
Two buses will pick up the residents to bring them to the event and then take them back.
Her homeless guests will then join the ladies and everyone will be treated to a meal of bourbon-glazed meatballs, goat cheese and roasted garlic bruschetta in the hotel's garden pavilion.More news: Dame Carolyn McCall departing easyJet for top job at ITV
Everything will be the same as it would have been had the wedding not been canceled, Cummins said, except there will be no head table for the bridal party, no cake table and no gift table.
"Everyone has done so much to give me the most wonderful experience and it just really sucks that they had to waste it", she told IndyStar.
For dessert, there's the wedding cake.
After the dinner, she will jet off to the Dominican Republic alone for what would have been her honeymoon.
Cherul Herzog, a spokesperson from one of the homeless shelters says the invitation from Cummins is very generous.
But with hopes of 150 homeless people attending, Cummins said she will "at least have some kind of happy memory to pull from" on what she once thought would be her wedding night.
"I'm happy through my grief and also Sarah's that she was able to make a selfless and very thoughtful decision in such a hard time", said Araujo, who would like for mom Kimberly Araujo, who recently passed away, to be remembered at the dinner.
As for her wedding dress, however, she said it has thus far been "too painful to think about" - but added that her fiancé's family had paid most of the wedding bill anyway.
