Of course everyone is unique when it comes to their body. I think what she means, though, is that she wants to know the standard measurements for her
bone structure so she doesn't aim for a size goal that's unreasonably idealistic. I would like to find out what mine is supposed be too. I mean, what's really unrealistic is when someone aims to be a size 3/4 when their build is not capable of becoming that small. That's where the measurements based on wrist size come in handy. I haven't met anyone who doesn't already know that it's only meant to be used as a guide for a person's size, not the absolute definition.
