Fusionette has 3 official costumes - or models - in the game that I'm currently aware of.
The first is the simple, straight-forward non-Vanguard costume that you see her in in Faultline.
The second is the one where she has a cape and some of the Vanguard costume options. You see this one in the Rikti Warzone.
The last is a non-combat NPC only outfit. A 'Little Black Dress' number that she wears in reception area of the diplomatic function part of the mission where you protect Lady Grey from Nemesis.
(Just to be a completionist/pedant - Jim Tembler/Faultline also has 3 models. His contact look in Faultline, his combat togs in RWZ, and a Tuxedo in that same Lady Grey mission.)
