If you consider the old Final Fantasies based off representations of Amano's anorexic art, they'd have to be light as a feather. They're barely more than bones and skin. Especially the females. Maybe for some odd reason they based their weight stats on that

And yeah. I think different people have different definitions of "curvy". I've known quite a few people use it in the context of meaning at least a little chubby. I really don't think it should be used as any kind of descriptor considering its general ambiguity these days
