Seems comprehensive. (I think you need some color in more places than the bat, to distinguish the Batgirls from all angles.)
OK, I have discovered I've been accidentally spreading disinformation, and have to make some corrections:
1) Bete Noire actually DOES wear a cape throughout the comic.
2) Tiffany wears a backpack, and also has a cape on the final page when she swoops in to catch the detonator. I think most of the cape must be tucked into that backpack for the entire story, because there's always some fabric around her neck.
These are very elaborate costumes so one can spend all day analyzing them . Like, what's the deal with the bracelet of beads Tiffany wears over her left gauntlet?
Seems to me Garron must have put so much time into keeping these suits unique and consistent that he just couldn't give things like the wedding scene the same amount of attention.
