To ease Meador's mind about being maid of honour, her sister, Deanna Adams, told Meador she could wear whatever she wanted.
"I already felt like everyone was going to watch me," Meador said, so she might as well have fun with it.
Leading up to the wedding, Meador and Adams would trade jokey texts about what she might wear: lederhosen or a steampunk outfit?
Adams said okay to the dinosaur, but Meador kept checking with the bride and groom, giving them the chance to veto her outfit. They never revoked their blessing.
Just in case, Meador had a backup: Under her T-Rex costume, she wore a $30 grey dress from Ann Taylor Loft, an affordable women's clothing store, purchased at a consignment shop near the wedding venue.
After the ceremony, she shed her prehistoric skin "because it was really hot," Meador said.
It was also a bit unwieldy for dancing: "If I moved, I was afraid I was going to knock someone with the tail."
Much cheaper than the standard wedding dress and not requiring alterations, the dinosaur was purchased for $100 on Amazon, Meador said.
"We're not all about spending a lot of money on stuff," Meador said of her family. "It's just a day. It's the marriage that counts."
Other members of the bridal party wore Converse sneakers and flip-flops.
After Meador posted a photo of the wedding ceremony on Facebook, the image went viral - getting thousands of likes, comments and shares.
Jezebel declared her "the Best Person in America." And of course, some of the comments were mean.
People accused her of showboating, but others defended her.
Adams also shared an image of the wedding party on Facebook, too, including an image of texts in which she approved the T. rex costume.
"I wasn't trying to steal my sister's spotlight," Meador said over the phone, adding that Adams looked so beautiful, "not even a giant inflatable dinosaur could distract from that."
After the big day, Meador gave Adams the costume as a wedding gift.
