“We’ve felt like a family for so many years. This just makes it official,” says the couple. “We are so lucky to not only be marrying our best friend, but to have family and friends from all over the world joining us to share in this day and celebrate with us.”

The bride – who wore a gown from the Inbal Dror 2014 Los Angeles collection – designed the wedding “from top to bottom” and paid homage to the couple’s favorite things: wine, traveling and music.

Later in the night, the newlyweds and their guests will celebrate their union while dining on a custom dinner by Chef Kevin Miller at Copper Kitchen and sipping on five wines handpicked by their favorite sommelier Ralph Hersom.
