Even though 17 states have approved same-sex marriage, the wedding industry remains geared toward heterosexual partnerships. Frederick Sullivan and Jaime Botello, creators of the Gay Vanity Fair, are addressing the issue. The one-day gay and lesbian wedding extravaganza — complete with a fashion show hosted by radio’s Joel Riddell, boutique vendors, caterers, hair and makeup stylists, venue representatives, tailors and giveaways — debuts Feb. 9 in The City at the Bently Reserve.
