Remember how the costume was blacked out before, and Batgirl was just a silhouette kicking people?
It's...got stripes? It's an interesting touch, and not at all what I would've expected. I'm kind of disappointed it's not purple all over (which would've made it similar to both the Batgirl costume from the 60s Batman show, as well as the Batgirl costume from The Batman cartoon). Ah well.
