Shouldn't her copy, you know...
Haha, I mean I know why Oda would cheat on her powers a little in this case for modesty, but she's never been able to replicate her clothes, just her actual body. Unless in the course of her training she managed to master that, which I can get behind, but...I'd like it to be acknowledged in that case, at least.
(Yes, I get hung up on silly details. Shh.)
