Her name is Laura Giraudi, and this was used on the album cover Super Cubaton 2013. Google her for more images like this. This image may well be modified, but probably not to adjust her proportions.
Rather, Ms. Giraudi and abclic are clearly both pros. She is posed with abs pulling against her curved back. This displaces her already spare midriff into her pelvic and thoracic regions, creating this stunning wasp-waist effect.
