Eh, its functional I suppose. Certainly not imposing, but it looks like something that would have actually been made by a vigilante on a budget.

She looks good. Her costume is exactly the same except instead of spandex, it's got kind of a trendy "hipster" leather jacket look to it. Which fits what they're doing with the character's personality, making her younger, more of a college student, which is what they probably should have done when the Nu52 started in the first place if they were gonna undo her being Oracle.
Normally I'd be against re-rebooting an individual character years late, but in this case, it's okay because the previous Batgirl run was terribly written and should be disregarded anyway.

I dont mind the costume.

Its the whole shes a hipster thing, screw that entire storyline with the brother who is a serial killer thing. No she is like taking selfies and being happy and shit.

Let me stress - Not against Batgirl being happy and shit. Just not this one. Not Babs.

I dig it. This is a character who has always has an identity issue and struggled to find a definitive, individual design. Is instantly identifiable as Batgirl, but plays with some contemporary ideas. Looks good. Works.

Seems like they're trying to make her younger and younger. Why not just use Steph tbh?
