Zam Wesell at Star Wars Weekends. I captured this in 2010.
From The wookieepedia:
Zam Wesell (pronounced /zæm.wɛzˈɛl/ or /zæm.ˈwɛs•əl/) was a shapeshifting Clawdite bounty hunter from the planet Zolan. In her true form, Wesell was a reptilian-like humanoid, although she often appeared as a Human woman with short blonde or bronze-colored hair. She trained in the ways of the Mabari warriors on her homeworld before eventually being labeled a heretic and fled to the commercial center of Denon. To escape, Wesell took the form of a Human woman and took a job in personal security. Over time, she moved up through the ranks by honing her skills, gathering equipment, garnering finances and making valuable contacts which altogether allowed her to begin a career in bounty hunting.
