A convicted mobster took time out from his sentencing in Manhattan federal court yesterday to needle a supporter for a fashion faux pas.

Reputed Gambino soldier Anthony Moscatiello did a double take when he was led out of lockup and spotted one man wearing a loud, pinstripe black suit in the courtroom gallery.

“You look beautiful. That suit must have been $5,” Moscatiello joked.

He was then slapped with 43 months.
