Imitation is the sincerest form of flattery — and in Kim Jong Un’s North Korea, that’s now an order!

All North Korean men are now required to get the same haircut as their nutjob leader — shaved close on the back and sides, with longer hair on top brushed back off the forehead.

The state-ordered guidelines were introduced in the capital, Pyongyang, roughly two weeks ago, according to South Korean media.

And the rule is now being enforced nationwide.

But not all of the dictator’s subjects are impressed with the strongman’s inverted bowl-style ’do.

“Our leader’s haircut is very particular, if you will,” a source told Radio Free Asia.

“It doesn’t always go with everyone, since everyone has different face and head shapes.”

Meanwhile, a North Korean now living in China said the new haircut makes Koreans look like Chinese smugglers.

“Until the mid-2000s, we called it the ‘Chinese smuggler haircut,’” the Korea Times reported.

Until now, Korean men could take their pick of 10 state-approved styles.

Women will still enjoy far more freedom to wear their hair the way they want — with a list of 18 looks the communist government has deemed appropriate.

And it’s not the first time North Korea has ordered its citizens to clean up their act, the BBC reported.

North Korea’s state TV once launched a campaign against long hair, called “Let us trim our hair in accordance with the Socialist lifestyle.”
