ALEXANDRIA, Va.– The tailor who made Paul Manafort’s infamous $15,000 ostrich leather jacket confirmed to The Post Wednesday that this black, hooded garment is the one that prosecutors point to as a prime example of the extravagant spending by the former Trump campaign chairman.

Alan Katzman spoke exclusively to The Post from his Jersey City, N.J., home after his son, Maximillian, testified against Manafort in a Virginia federal court.

The younger Katzman, who managed his father’s Alan Couture shop on West 57th Street in Manhattan, told jurors that Manafort spent more than $900,000 there between 2010 and 2014.

Invoices from the store entered into evidence Wednesday show that Manafort and his wife, Kathleen, also bought a $9,500 ostrich vest and an $18,500 python coat from Alan Couture.

“The brown is python, for Mrs. Manafort,” the elder Katzman said of a picture of the brown leather jacket that the feds entered into evidence Wednesday.

Maximillian testified that Manafort wired funds from banks in Cyprus to pay for his purchases.

Justice Department Special Counsel Robert Mueller alleges that Manafort stashed millions of dollars he was paid by pro-Russian, Ukrainian pols in Cypriot banks to avoid paying takes on the money in the US.
