dr. luigi
An official alternate costume for Luigi in the Dr. Mario series, dressing him up as a doctor. Luigi wears a lab coat with a white collared shirt, white pants, and a green necktie, and has a stethoscope around his neck. Notably, Luigi often retains his signature cabbie hat, though several games do swap it out for the usual head mirror common to the series.
