Randy Fenoli once knew the perfect dress for a bride just by looking at her

• Insider spoke to Randy Fenoli, who is starring in the 20th season of "Say Yes to the Dress."
• Fenoli told Insider he once picked a dress for a bride the moment he saw her.

It's no secret that Randy Fenoli has a knack for knowing what type of wedding dress will suit a bride thanks to his decades of experience as a designer, consultant, and fashion director at Kleinfeld Bridal.

But the "Say Yes to the Dress" star told Insider that he once took his skills to the next level by knowing the perfect dress for a bride the moment he laid eyes on her.

"In St. Louis one time, years and years and years ago, I was running around in this bridal salon," Fenoli said, as he was in town for a trunk show.

"I passed by the front desk, and there was this bride standing there. I looked at her and I said, 'Oh my God. Are you a bride?'" he told Insider.

After she told him she was, Fenoli replied: "I've got your dress."

Fenoli then brought the bride one of his own designs to try on, though the sample dress wasn't in pristine condition because it had been used for photo shoots and runway shows.

"I said, 'Just try it on, and I'll wait outside the room.' And I waited and I waited and I waited and nothing," he said. "Finally, I knocked on the door, and they opened the door and she's crying."

"I thought, 'Oh God, I didn't ask her budget. I didn't ask what she was looking for. I don't know what's going on.' I freaked out immediately," he said. "She was just bawling."

But it turned out the bride was crying because Fenoli had brought her the wedding dress she had been dreaming of — literally.

"She reached down into her purse and pulled out and unfolded the picture of the dress that I put her in," he said. "That was the dress she came in for."

Fenoli thinks his decades of experience in the bridal industry have helped him become attuned to brides' needs.

"After doing it for so long, you just see a woman's body and her hair color and her eyes and her personality and you just gravitate toward a certain dress," he said.

Fenoli is currently starring in the 20th season of "Say Yes to the Dress," which airs on Saturdays and includes a special episode in which Fenoli reflects on the series.

You can watch new episodes of "Say Yes to the Dress" on TLC on Saturday at 8 p.m. ET and afterwards on Discovery+.
