In my opinion, there are several ideal female body shapes. It can be any body type, such as hourglass, thin and toned, or more musclar... the thing they all have in common is that they are FIT bodies. Naturally there are different shapes due to bone structure, genetics, etc. But all the bodies I admire are relatively slender, with some degree of muscle tone/definition. I don't think muscles are gross in women, in fact they look good!
But those female body builders with big bulgy muscles and veins... YUCK!
