When a bride-to-be told her sister she could wear anything she wanted to the wedding, her maid of honor made an unexpected choice: a T. rex costume.

Deanna Adams, 40, a legal administrative specialist in Omaha, Nebraska, said her wedding was supposed to be “low-key.”

“I didn’t want to make a big deal out of anything, as long as I got to wear a dress, have some cake and get some great photos,” she told TODAY Style via Facebook.

But what started off as a joke soon became reality when Adams’ sister, Christina Meador, 38, had a hilarious idea for her maid-of-honor look.

“Christina sent me a text a year ago saying, ‘I found my dress!’ followed by a link to the costume on Amazon,” Adams said. “I thought it was hilarious and told her she had to do it. It then became kind of a game of chicken⁠ — I don’t think she expected me to be cool with it.”

Meador ended up wearing the look on her sister’s big day and, thankfully for us, there are lots of adorable photos as proof.

“They definitely knew how to make a wedding memorable,” Andrea Nuxoll, the wedding photographer, told TODAY. “It’s nice to have some diversity in your wedding.”

Adams seems to have taken the joke in stride. “We easily joke with each other and definitely don’t take much too seriously,” the bride said of her relationship with her sister.

“I know she’s got my back, and I’ve got hers,” she added.

After the big day, Meador took to Facebook to share a photo from the wedding.

“When you’re maid of honor and told you can wear anything you choose…I regret nothing,” Meador wrote alongside a photo from the ceremony. The photo has since been shared more than 37,000 times with more than 10,000 comments.

“I hope the look catches on ⁠— you and your sister are fabulous,” wrote one fan of the post.

Another added: “The bride and groom are AWESOME for letting everyone do their own thing.”

On what she hopes people take away from their story, Adams said it’s all about joy.

“We’re just glad it made so many people smile,” she said. “We really didn’t think anything like this would happen.”
