As we know,in One Piece almost all the women are drawn with great bodies,so its hard to judge on that,because they are just all hot.
They are also often strong women,and smile a lot,so even these two traits are very common in them,and its hard to choose someone only on that
What makes the difference,then? Something like a sexy attitude,a more seductive attitude!
And,in this field,i think the champions are:
-Califa
-Stussy
-Sandersonia
-Reiju
-Doll
-Robin and Hancock when they were "evil"
They have that sexy attitude!
Also,Margaret and Hibari deserve a mention as they are wife material
