"Traditionally meaning 'the totality of being female.'" (A word borrowed from the native American Indian language, and written phonetically. In recent years it appears to have taken on a derogatory connotation, but is now being reclaimed for its original intended usage.)
I like that definition, which I think possibly explains the connection between the images and the association. In many ways, these images are not 'flattering' in a typical sense. (Society is addicted to the notion that thin is beautiful, after all). But that is one of the joys of pregnancy. There is absolutely no point in vanity; it is probably one of the few times in life when a woman can be completely, unashamedly honest about appearance and body shape, without any need for excuses.
It is challenging knowing how to pose with a completely different body shape, since 99% of 'standard' art nude poses simply don't work. But it's also refreshingly liberating to be able to pose without trying to elongate myself or appear narrower in the waist.
This may possibly be the only time in my life I celebrate my body and all its curves doing what nature intended it to do... who can say? So, 'flattering' or not, I like these images.
