Victoria’s Secret’s exit from the swimwear business is hitting customers like a $500 million punch in the gut.

While word leaked last month that the $7.7 billion lingerie chain was ditching swimsuits from its stores and website, the emails and social media posts from the company officially announcing the move on Wednesday sent customers into a tizzy.

One longtime customer, Jamie Gorman, told The Post the only things she ever bought at Victoria’s Secret were swimsuits.

“I probably won’t be shopping there anymore,” she said.

“This is a bad move,” Lisa C. posted on the retailer’s Facebook page, referring to the swimsuit exit.

“Guess I will have to attempt to find a place yet again that has stuff I love wearing,” Liz O. complained in a Facebook post.

“Really stupid move on the company’s part to get rid of the stuff that is bringing us in,” Harmony C. added.

“Please reconsider keeping your swim line!!!!” Missy D. wrote on Facebook on Wednesday afternoon. “I buy all of my bathing suits from here and have no idea where I will buy them anymore if you discontinue them!!!”

The Columbus, Ohio, chain sold roughly $500 million in swimsuits a year — out of $7.7 billion in revenue last year.

Investors have known for about a month that Victoria’s Secret is retrenching to focus on its lingerie business after a stretch of poor financial results.

Shares of L Brands, the parent company of Victoria’s Secret, gained 3 percent, or $1.90, on Wednesday, to $66.16 — but shares are still down 31 percent this year.
