American Apparel’s days as a Los Angeles-based manufacturer are numbered, sources close to the company told The Post on Monday.

The 27-year-old teen retailer, which boasts on its website that its togs are “Designed, Cut and Sewn in Los Angeles,” is making plans to pull up stakes and move east — possibly to North Carolina or Tennessee, where the minimum wage is $7.25.

In California, the minimum wage is set to rise to $15 by 2020.

American Apparel, which emerged from Chapter 11 reorganization in February, is scheduled in October to close its second factory this year.

The facility at 1020 E. 59th St. in Los Angeles makes knit fabric. Its closing will force 50 workers from their jobs, according to a letter sent to employees, a copy of which was obtained by The Post.

In February, the company closed another facility that handled the dyeing of fabrics.

Known for its provocative ads and its ongoing legal saga with ousted founder Dov Charney, American Apparel once operated six factories. The lease of its largest factory, which doubles as its downtown LA headquarters, expires in 2019.

The company does not plan to renew the lease, sources said.

A spokesperson for the company declined to comment on a potential move — noting that the knit factory is closing because “our lease has expired.”

This comes on the heels of a massive layoff in April, when 500 workers were laid off and the company began to outsource its denim production.

At the time, Chief Executive Paula Schneider told employees that the company would be making fewer garments this year to cut down on inventory in stores where sales are falling, according to a report in the Los Angeles Times.

“They are looking very aggressively to relocate to the East Coast, probably in the next year or two,” said a source close to the company. “To move an operation of this size will take a lot of planning.”

In the meantime, American Apparel continues to struggle financially.

The company had $9 million in cash on hand as of March 31, according to court filings, less than half the amount it had three months earlier.
