Calling all Jewish bridezillas!

Hundreds of stressed-out kosher couples are set to descend on the first ever “Big Fat Jewish Wedding” expo in Park Slope today to plan their magnificent wedding-day celebrations.

From a dizzying array of prospective rabbis to high-end wigs for the fashion-forward Lubavitcher, organizers promise that even the choosiest of the chosen ones can find whatever their Hebrew hearts desire.

“The goal is to serve as many of the Jewish sects and backgrounds as possible,” said 24-year-old founder Avi Werde. “This has never been done to this scale for Jewish clientele.”

Werde said he expects more than 500 couples to select from a wide variety of wedding singers, caterers and gown makers at the expo, which is taking place at Brooklyn’s Grand Prospect Hall.

But don’t expect any plunging necklines and tight fits — a catwalk fashion show will present dresses marked by modesty. That means hemlines to the ankle, long sleeves, and an appropriate amount of snugness.

From Hasidim to the reform, Werde said that every Jewish group will be represented and that rabbis of all backgrounds will tout their officiating talents to prospective clients.

“I want the experience of your wedding to be memorable and enjoyable to you,” Werde said. Brides and grooms can ask them questions, like what is your style of officiating? What is your background? The idea is if they need a rabbi, they’ll be able to walk out with one.”

Werde said that younger Jews are starting to break free of traditional wedding rituals and are pining for increased flash and variety on their big day.

“Just because our parents did things a certain way doesn’t mean we want the same thing,” he said.

Set to get hitched in February, Adina Engel, 32, said she is putting together a dream dress that will be equal parts sexy and sedate.

The schoolteacher plans on modifying a suggestively sleeveless gown by covering her bare arms with stylish lace.

Admitting to some Bridezilla tendencies, Engel said the all-inclusive expo is nothing short of a godsend. “I went to four different DJs,” she said.

Rochel Rosen, 25, a Hasidic Jew from Crown Heights, said the expo’s convenient one-stop schlepping will help to tame her inner bridezilla.

“It’s all about the little details,” said the lovely Lubavitcher. “The idea of having all the wig places in the same place, to have all the caterers, and events planners together, really cuts down my stress.”
