Something borrowed, something blue — but nothing with animals.

When Jennie Wilson of Soho got engaged in December 2014, the former Oakland Raiders cheerleader didn’t hoof it to any of Manhattan’s posh shoe boutiques to shop for wedding-day stilettos. Instead, she called on French cobbler to the stars Christian Louboutin to personally design a pair for her.

The catch? They had to be vegan.

“I always intended to wear Christian Louboutin shoes on my wedding day,” Wilson, 30, told The Post.

But that dream was nearly dashed by her going vegan in May 2015.

“I did not want an animal to die [just so I could wear] its skin as leather,” she explained.

It took months for Louboutin to find materials that met both Wilson’s wishes and his exacting standards, and to figure out a cruelty-free construction — right down to his trademark red soles.

“Once [Louboutin] determined they were able to source the materials, it was seamless,” Wilson said.

The painstaking procedure began with the task of making casts of Wilson’s feet. Typically, the made-to-measure process takes five weeks and prices begin at $3,400, according to W magazine. (Louboutin and Wilson were both mum on the price of her haute couture heels.)

The end result was a pair of peep-toe platforms towering on 5.9-inch heels and made from a pale pink satin-like fabric in the designer’s Paris atelier.

Louboutin even threw in a sparkly clutch-style purse — also vegan, of course — as a gift, with a handwritten note wishing Wilson and her fiancé, Richard Smith, 30, a sales professional, luck on their June 11 wedding.

Wilson also wore a custom vegan dress by coveted bridal designer Galia Lahav, and served an animal-free feast following the nuptials at the Château d’Ermenonville castle near Paris.

Lest the 60 guests wonder why they were dining on semolina cabbage flower rather than steak, she and Smith, also vegan, sent out letters beforehand explaining why veganism was important to them.

“When it came time to choose the meals for our wedding events, we were both torn,” Wilson said. “Do we adhere to what the majority might expect even though it is no longer aligned with our beliefs? The answer was no.”

The affair may have been cruelty-free, but the couple’s bank account still took a beating.

Wilson admits the cost was “well over $100,000.”
