The bigger round part (where the word piqued is) is he shoulder - kind of shrugged or hunched up, and the line under the wrinkled fabric is the line from the shoulder to his neck - I think. So there is a gap above the line where the shirt is pushed up and below the line is the area leading to the collarbone.

Yeah, I see it now :P
I had trouble seeing the gap as a space of nothing and was wondering what the heck it was xD. And the fact that we don't see his neck or even his jaw line at all didn't help me on thinking that it was actually his shoulder.
As for the shirt I was starting to think it was a skirt :V.
So that was complete wtf.
It's been puzzling me since forever, might as well just ask.
What is the things on the bottom right panel supposed to represent? Like, where there is the PIQUED!.
