Lindsay Hubbard, Star of Summer House, Auctions Wedding Dresses for Charity After Broken Engagement-quang

"I bought these dresses out of love and they deserve a second home out of love," Hubbard said, sharing how the sale will be her "final step" in her healing process

Lindsay Hubbard is giving another bride "something old" for their big day.

On Thursday, June 20, the Summer House star, 37, announced her partnership with KleinfeldAgain.com to sell the three wedding dresses she planned to wear at her own ceremony with Carl Radke before he suddenly called off their engagement in August 2023.

"I was talking to the girls from Kleinfeld, just telling them that I needed to sell my wedding dresses and they were like, 'Funny you should mention that because we're launching a website for that,'" Hubbard told PEOPLE at the partnership launch in New York City on June 17, 2024.

"These dresses were just sitting in my closet waiting for me to figure out what to do with them," she says. "I thought the reunion and watching the reunion was going to be the final step in my breaking up process, but it was a whole year of reliving and rewatching and talking about it over and over and this is the final step for me, getting these dresses off my hands," she continues.

During the launch, Hubbard told the crowd she was ready to move on and give the dresses to another bride.

"Thank you for celebrating this final step in my healing process. It's exciting, I bought these dresses out of love and they deserve a second home out of love."

All of the proceeds made from the sale will be donated to Chick Mission, a non-profit organization that helps women with cancer freeze their eggs before starting treatment.

In addition, KleinfeldAgain.com will match the proceeds of the gowns to be donated to The Chick Mission. 

After getting engaged in August 2022 and planning to tie the knot in Mexico, Hubbard and Radke called off their engagement and canceled their nuptials.

In a letter to family and friends obtained by PEOPLE, Radke, announced the news and asked their fans and loved ones for "patience and grace" to heal from their broken engagement.

"There have been a lot of false narratives and misunderstandings that have made this all the more painful but sadly at this time we are not moving forward with the wedding," he wrote at the time. "The fact of the matter is Lindsay is devastated and I'm crushed with how all this transpired. I graciously ask for some patience and grace to heal and recover while we navigate this extremely difficult time."

In February 2024, Radke and Hubbard's Summer House costar, Kyle Cooke, told PEOPLE that the couple had problems leading up to their split.

“There were big fights, like volcanoes,” Cooke recalled, sharing how he saw “red flags” in Radke and Hubbard’s relationship “that dated back to the first couple months of their dating.”

“I saw things that concerned me, but how do you find the right time and place to confront not just Carl, but Lindsay, too?” he continued. “These are both my friends and you're kind of caught in between this weird place where you don't want to just speak your mind. You might say something that could jeopardize your friendships. Sometimes I'm not very eloquent with my timing or my wording, so I have to pick and choose my battles.”
