He’s missing his Bonnie Parker.

Police are on the hunt for this Panama hat-wearing man — who allegedly robbed a Long Island bank on Monday before strolling away on foot.

The off-trend suspect — who bizarrely paired his “summer style fedora” with a blinding blue T-shirt, dark jeans and black shoes — walked into the Miller Place Chase Bank at 385 Route 25A around 2:40 p.m., and flashed a note demanding cash to a teller, Suffolk County Police said.

The employee handed the man cash from the drawer and he then fled, in a robbery that took about two minutes, cops said.

Other people were in the bank at the time and no one was injured.

Police wouldn’t say how much the crook stole, citing the ongoing investigation.

He was described as being in his late 20s to 30s, of average height, medium build and wearing dark rimmed glasses and a full, dark beard.
