It doesn’t look like there’s been any Photoshop wizardry done there. Good job Serena!
The same, however, cannot be said for this image:
Look at her stomach. Look at the red inner tube. See how it’s fuzzy and distorted? I smell some Photoshop fuckery!
If you’ve gotta Photoshop a picture in order to feel good about putting it on Instagram…you probably shouldn’t be throwing that photo up in the first place.
