Spot the difference: Kim K vs Kim K

Yesterday Kim Kardashian posted the photo on the right of herself from her 'skinny days' on her instagram page, saying she's getting back into training so she could look like that again. She wrote; "Throwback to a few years ago #SkinnyDays #OnTheTreadmillRightnow".What she didn't count on was that people will notice the difference between the photo she posted and the original image (pictured left). Trust the fans, they were quick to point out the difference, accusing Kim of Photoshopping the image.
Can you spot the differences in the photos? From the zip on the dress, her arm, the nose...what else?
