... It's possible. [She's seen B-mode too, and it's not like she knows for sure, but. It's not impossible at least..........] Although that wouldn't be my guess.

[She pauses for a moment, considers how much she should really say. This isn't really her story to tell, is it? Not to mention that even if 2B trusts A2 with her life (and literally, she did), she still doesn't know that much about her predecessor's past. And that's always suited her just fine. If A2 ever wanted to share that, she would. If she didn't, she wouldn't. Simple as that.

Besides, should she really be telling a human about this? Even if this girl somehow is inheriting A2's memories. Something about it just doesn't sit right with her, a human somehow turning into an android. Then again, if she's going to receive these memories, it'd be better to understand them, right? She makes her decision.]

Presumably, A2 did have a uniform like mine at one point. However, after she deserted YoRHa, that meant she also lost all resources and supplies they provided. I assume that after years of fighting machines on Earth, her clothing simply wore away with time.
