penguin suit

Black-tie evening wear

A penguin suit is informal for a man's black-and-white formal outfit—tuxedo or tailcoat with white shirt—evoking the bird's coloring.

The term often carries a note of reluctance or mockery: I have to squeeze into a penguin suit for this wedding.

It suggests the wearer finds formal dress uncomfortable or pretentious.
