Damian - give him a Suit in the classic Robin colors
Jason - it is probably time to ditch the "Mortal Combat Suit", and the should also redesign the Robin costume here wears in the Flashbacks (if Dick can have Pants in World Finest, Jason should also get an update)
Cassandra - it makes no sense that she is still wearing Helena's improvised Batgirl Costume from No Man's Land
Helena Bertinelli - ditch the coat and give her the cape back
Signal - his suit is just not a great look
