She got more than a brief shock.

A stunned New York woman says she discovered a used thong in the pocket of her brand new jeans.

Christine Evans said she found the panties in a pair of Not Your Daughters Jeans she’d bought from Nordstrom.

“After, many years of loyalty to your company, I was appalled at the lack of customer service you gave me when I received a pair of Not Your Daughters Jeans with a DIRTY and WORN women’s THONG in the front pocket,” Evans tweeted at the company Tuesday.

Evans said she was offered a replacement pair – but wrote that wasn’t enough.

“I would imagine that a company such as this one could do more for a loyal, card-holding customer. As a nurse, the numerous amount of health hazards this issue presents is astounding,” she said.

The luxury department story apologized and said they were hoping to get to the “root of the problem.”
