Who said teens are fickle?

Perhaps it was Abercrombie & Fitch.

The struggling retailer, which also owns Hollister, got slapped by Wall Street on Friday after it delivered lousy third-quarter results, in which revenues were down 6 percent and same-store sales were down a whopping 14 percent at its namesake brand.

It marked the third straight quarter of lower same-store sales.

Investors ran for the exits, pushing the stock down 14 percent, to $14.60.

“Not only do we maintain our belief that a material turnaround in the company’s performance is not on the near-horizon, but we believe that the company offers little long-term return potential,” wrote Wunderlich analyst Eric Beder in a report.

For years A&F sold its heavily logoed apparel using hunky, shirtless (sometimes bottomless, too) male models in its marketing materials. Its female models were also scantily clad until last year, when it began a rebranding effort to assume a more mature posture.

At Hollister, sales were flat in the quarter compared with a 2 percent sales decline in the previous quarter.

Overall, profits cratered 81 percent, to 12 cents a share. Wall street expected 20 cents.
