Jordan Bowen and Luca Marchetto of JordanLuca Marry at Their Milan Show

Before there was JordanLuca, the fashion line, there was Jordan Gene Bowen and Luca Marchetto, the couple whose first hookup 15 years ago inspired peals of laughter at their Jan. 18 wedding celebration.

Both were 25 in December 2010, when they locked eyes at the now-closed gay bar the Joiners Arms in London’s East End. Mr. Marchetto, who had recently moved to London from his native Italy, was on a date with a man Mr. Bowen had gone out with weeks earlier. Mr. Bowen, whose date with the man had been a nonstarter, couldn’t get over Mr. Marchetto’s outfit.

“He was wrapped in a cashmere blanket with a backward baseball hat and sneakers,” Mr. Bowen said. “I thought, ‘Wow.’” Instead of ignoring their mutual attraction — Mr. Marchetto was taken with Mr. Bowen’s style, too, especially his vintage Westwood McClaren pants — they secretly exchanged phone numbers in the bathroom.

Minutes later, Mr. Marchetto told his date he wasn’t feeling well and needed to go home. He then climbed into a cab and hurried to the Liverpool Street bus station, where he and Mr. Bowen had agreed to rendezvous. “We met around 3 in the morning and kissed for ages,” Mr. Bowen said. Mr. Marchetto remembers getting home at 7 a.m. in a fog of lust, beaming over his incredible good luck.

“Jordan had told me during the kissing that he was a milliner,” Mr. Marchetto said. When his roommates started stirring that morning, he told them the good news — that he had met a “a very hot millionaire” from Notting Hill. “My English was really bad at the time,” he said. “I didn’t know what a milliner was.” (He soon learned his new crush made hats.)

Mr. Marchetto and Mr. Bowen, now both 40, started their fashion line, known for boundary-pushing men’s wear like a 2023 T-shirt mapping London’s cruising spots, in 2018 from their kitchen table. Both had developed an interest in clothing and accessories years earlier, but from different points of view.
