She’s gone from horse and buggy to bra and panty.

Raised Amish, Kate Stoltz (née Stoltzfus) left her insular Pennsylvania community for New York in 2012 to film the TLC reality show “Breaking Amish.” Since then, she’s moved to the Big Apple full time and has been snapped up by Major Model Management. Last July, the 23-year-old posed in midriff-baring tops and short shorts for Maxim, but Stoltz’s shoot for The Post is her most revealing yet.

“A year ago, I never would have done a lingerie shoot,” says the single stunner. “I don’t know if I’ve become more comfortable with myself or with the idea.”

Her Amish parents—unlike many people who leave the faith, she continues to see them twice a year— still aren’t comfortable with their daughter’s chosen profession.

“They know what I am doing but they … avoid the subject,” adds Stoltz,who made her New York Fashion Week debut two weeks ago modeling Cesar Galindo’s designs. Not that modeling is all she wants to do: She also hopes to pursue a business degree. (Stoltz has her GED.)

The 5-foot-8-inch beauty lives in the Garment District, where she has adjusted to modern conveniences, like her iPhone and computer, but still doesn’t own a television.

“I don’t think [TV’s]a waste of time, but right now I have so many things I want to accomplish, it’s a distraction,” says Stolz. One thing keeping her busy?A spinoff on TLC, “Return to Amish,”debuting in June.

While she’s no longer a wide-eyed innocent in the city, there is one holdover from her old life: Lingerie.Yes, it turns out the Amish often wear pretty underpinnings beneath their modest garb.

Explains Stoltz: “My aunt once said, ‘I can’t wear nice dresses, but a good pair of underwear always makes me feel like I look good, even if I’m the only one that knows it!’ ”
