The Reps are councillors for the Gungan people and assist the Boss in taking decisions. As such, each of them wear the same traditional outfit as we could see in the Phantom Menace and the Clone Wars. At the time of the invasion of Naboo by the trade federation, the four Reps were Slarm, Been, Teers and Lyonie, who would later become Boss. Despite wearing the same dress, they were still distinguishable by the specific shape of their eyebrow bones.
Their outfit was composed of brown robes with traditional pattern from Otoh Gunga on the front, and a face mask. Figurines also depicts Rep Been holding a specific ceremonial staff.
