If you want to look suave in a suit this Halloween but still get into the festivities with a frightening look, consider this Joker costume starring Jared Leto in Suicide Squad. This suit is pretty cool, starting with a shiny metallic tuxedo. Underneath is a silky red shirt which is left mostly unbuttoned to show off the Joker’s assorted tattoos. The pants are simple black slacks. The real trick is in the face makeup, as you’ll want to die your hair a neon green and make your lips look bloody.
