The bride told ET back in December that she was planning a winter wonderland-themed wedding, complete with "whimsical" touches, lots of pale pink, deep red and moss hues, and a classic gown.

"It's very me," she said of the halter-top dress, which featured a long train. "It's a big dress. It's not like mermaid fit. I didn't really want sleeveless, so I did more of a sleeve thing. It's just so beautiful! The back's my favorite."

All of The Voice alum's bridesmaids wore white, while Davis' groomsmen looked dapper in three-piece charcoal gray suits.

Guests were asked to don black tie attire with fur for the celebration, which took place on a Franklin plantation set on nearly 200 acres. They were treated to a buffet-style reception catered by Nashville's Big Al's Deli, which included BBQ chicken, pork chops, corn cakes, shrimp and grits, macaroni and cheese, green bean and butternut squash soup.

RaeLynn gave fans a sneak peek at the behind-the-scenes prep work that was going on just hours ahead of her ceremony, captioning her Instagram, "It takes a village."

RaeLynn rose to fame after competing on Team Blake during The Voice's second season in 2012. She's remained close with her mentor and his ex-wife, Miranda Lambert, over the years, recording songs with the former and joining the latter on multiple tours. A source tells ET that Lambert was invited to RaeLynn's nuptials, but did not attend.

"I talk to both of them," RaeLynn previously told ET, confessing that even as their own marriage ended, the former couple had wise words of relationship advice. "It's all about when you find the right person, you gotta kinda go with it," she said. "They've been both so supportive."

As for Shelton's new love, Stefani, Rae gushed about the "awesome" pairing. "They're both great people," she said.
