Christian Siriano talks to HELLO! about picking your wedding dress

The TV host looked dapper in a custom Prada suit, while Lydia stunned in a custom Christian Siriano gown featuring a pink ombre skirt. While discussing his bridal collection with HELLO! earlier this year, the designer said, "I think [ombre's] a really beautiful technique."

The 31-year-old gave fans a sneak peek of her dress last week when she posted a photo of herself wearing the gown and staring wistfully out of a window. She captioned the black-and-white photo, “I am truly blessed to have you in my life @hardwick. I love you, and I will never stop loving you. I cannot wait to marry you in one week."

For their nuptials, the couple's florist drew inspiration from their favorite sci-fi and comic book series, by incorporating red roses, Tardis blue hydrangeas and Vanda orchids into the wedding. Celebrity wedding planner Mindy Weiss also had water bottles designed with the pair's initials in the shape of a Tardis.
