Tarryn Pitt loves scouring thrift shops for treasures, from vintage canning jars to velveteen armchairs. “I’ve been thrifting my whole life — it’s one of my favorite things to do, at least once or twice a week,” she said. “Pretty much all of my home decor came from a thrift store.”

She was browsing in secondhand stores where she lives in Prineville, Oregon, when she got an idea about her upcoming wedding. The average cost of a wedding in the United States is about $33,000 — an amount she said she found extravagant and also created a lot of environmental waste.

“I wanted something that was unique and fit my personality,” said Pitt, 25. “A thrift store wedding dinner seemed like the perfect answer.”

She and her fiancé, Holt Porfily, are inviting 307 guests to their outdoor mountain wedding in Sisters, Oregon. All of the wedding tableware and decorations at the outdoor meal will be thrifted.

“It’s honestly not just about saving money for us, though,” Pitt said. “What we’re doing is super sustainable, and I love giving old things new life.”

So far, she said, she has spent less than $2,000 on her wedding dinnerware and decorations, about half of what she priced out to rent similar items.

In late December, she posted a TikTok video of some of the plates she had found during one of her thrift shop excursions. Pitt said she was shocked when the video received more than 3.6 million views and 2,200 comments.

Pitt said the response has been so positive that she now plans to keep only a few plates after the wedding, and she hopes to rent the rest to other interested brides and grooms. She said she will keep the price low for obvious reasons.
