Brown, 23, is the daughter of Sister Wives‘ Kody Brown and his third wife Christine.

The bride wore a satin and beaded dress by Alfred Angelo for the ceremony, which was held outside with a view of the mountains as the backdrop. The 400-person reception was held inside the chateau-style restaurant’s greenhouse.

As a nod to Thompson’s Scottish heritage, his mother made hats for all four of Brown’s mothers, while the groom and Brown’s father Kody both father wore kilts.

The couple, who first met during a family party at her parents’ house, opted to go without a bridal party but still had Brown’s younger sister Truely as a page and Ariella as a flower girl along with Thompson’s 10 nieces.

For their vows, the bride and groom wrote their own messages and did not exchange rings since they’ve already been wearing them for some time. They also chose to have a handfasting ceremony, a Celtic tradition in which couples bind their hands together during the wedding to symbolize their connection and devotion to one another.

As for why they chose their venue, “It’s beautiful on its own, so we didn’t have to do much,” Aspyn says. “There’s flowers, a beautiful view and a pond. We didn’t have to do much for décor because the venue is already great on its own. It takes away from us having to worry about a lot of details and allows us and our families to just enjoy it.”
