If this was a drawing I'd say it had bad anatomy. @.@ The way her hips are twisted to where they don't even look like they are attached to the torso looks so painful. It's a lovely photo, but ouch. Maybe this pretty lady is just super flexible?
This is a quite classy form of sexiness. Not so sure about the angle or expression of the face, just doesn't look right to me but the outfit is really cute and the colors are a perfect blend of sunshine and happiness ^3^
