What a heel!

Amanda Keisoglu went to a Manhattan hot spot for fun and ended up the victim of a stabbing — by a stiletto.

Keisoglu, 26, was out on the town for her cousin’s bachelorette party in August when the group of 12 friends and relatives hit the Ganse­voort Hotel’s rooftop bar, Plunge.

They’d paid extra for a private ­table and were having a blast, Keisoglu says, despite the allegedly drunken, violent antics of a woman nearby.

“I didn’t know her whatsoever,” Keisoglu told The Post.

When the woman, Marie Thys of Belgium, got into a fight with someone next to her, Keisoglu tried to distance herself — but Thys had other ideas.

“I felt my wrist get pulled, and it forced me to turn around,” Keisoglu recalled. “Then she kicked my inner thigh.”

Thys struck with her stiletto heel just so, puncturing Keisoglu’s leg, leaving the shoe stuck in the wound until someone pulled the drunken woman away, Keisoglu said.

The bloody fashion attack left the New Jersey woman stunned.

“I felt hot liquid,” she said. “I sat down and plugged [the wound] with my finger.”

Bleeding heavily, a friend helped her to the restroom, and eventually the dental assistant was rushed to a hospital for intravenous antibiotics, but the wound was too deep for stitches.

Keisoglu, who was laid up for three or four days and still undergoes physical therapy, has filed a $5 million lawsuit against Thys and the Gansevoort for failing to prevent the attack.

“I thought I’d be safe there,” she said. “I feel like this could have been prevented.”

Thys, who was in New York on vacation, was arrested and charged with assault in the incident. The case is pending.

The Belgian woman “was visibly intoxicated for several hours prior to the attack” but the bar continued to serve her, failing to give her the boot even though she was “belligerent and violent against other ­patrons for some time prior to the attack,” according to the Manhattan Supreme Court papers.

“They completely failed at keeping me and the other girls safe,” Keisoglu said.

The Gansevoort did not return a call for comment.

A lawyer for Thys declined to comment on the lawsuit.
