No not at all. It's the recipe of the mix of the colors, pose, expression and yes sexy in awesome, but what constitutes sexy does not necessarily mean being naked of half naked... it goes slightly deeper then that. At least from my artistic perception.
Wonderful photo. The sassy attitude combined with the beautiful presentation of the model's curves draws the eye in deliberately. I found myself looking all the way up her legs, admiring every curve, and getting hit by those eyes. The composition is such that it makes the viewer a little uncomfortable by the upper crop being low (like a low ceiling) and the model's expression, but drawn in by her curves and eyes.
