I Have So So Many Questions

I ran into these panels while sourcing something from the same comic and... I have many questions.

One of which is, Diana was absolutely drawn naked originally right?  Because that "nightie" she's wearing is just barely sketched on her otherwise naked body.  It's basically just a few frills drawn at her hips and a few lines on her body so you don't think she's naked.

And then there's "what the f- is happening to her body in that second panel?" (or really in any of those panels)

And also... what is she trying to do with that sword?  Is she just showing it to him to distract him?  "Look at my cool sword! Ignore that my body turned into a Tetris block!"

Many... MANY questions.

(Panels from Wonder Woman vol. 2 #0, DC Comics)

PS: also happy Canada Day if you celebrate, sorry for the horrors... or you're welcome for the horrors if you like them
