I know it doesnt mean much from someone with 2-3 posts, but I can confirm that the author's comment on the video "MayLee" existed near the time when the video was first uploaded. It never said it was her name, but it's a plausible inference.
Another interesting piece of information is that the video has been edited since its inception on youtube. Originally, the video started with a photo of a girl in that same tee(and probably the same jeans), about of a similar build to the girl in the video, except with(you guessed it) -substantially smaller- breast size, probably an A or B cup. This could, however, simply have been a picture of a different model in, say, a magazine, with the t-shirt on. The head was cropped, so there's no way of being sure.
