Actually i don't think so.
The only part of the image with noise is her panty. Anything else is clean. This noise is usually created when re-saving a web-quality image like a jpg in photoshop.
I'm certain that is photoshop. Maybe coz I use it for a living. I could fake a thin line and modify the hue to a redish colour to make it seem like her panties are more se-through than they actually are…in seconds.
I do think she will show skin in the future, but i feel they would prefer to do a 'light' photoshop work to the images for a little while, after awhile of some simple photoshop tease, she will show skin.
