I think Dora was just warning everyone because some people are very touchy about things like that. Had she not warned us, there was the possibility of someone saying OMFG YOU CAN SEE NESSA'S BOOB WHAT SKANK!!!!!!!!!!!!!!!!!!!!!!!!1111111 I appreciated the warning, myself, or else I would've clicked on the picture and been like HELLO 8O 8O
How it can be disrespectful I have no idea. Like Rosie said, I'm quite sure she knew her breast was showing in a shirt like that. You'd have to be pretty stupid not to, and I tend to think of Nessa as an intellegent person.
