This thief should win most valuable costume.

A man robbed a bank in Midtown Manhattan on Friday, disguising himself in a construction worker getup worthy of the Halloween holiday, law enforcement sources said.

He was seen on surveillance video walking into a Chase Bank at 787 7th Ave. just before 3 p.m.

Wearing white gloves, a hard hat and an orange vest, the robber passed a note demanding money to a bank teller, who handed over an undisclosed amount of cash, police said.

The man then fled the seen — and no arrests have been made yet, according to cops.
