Rhiannon is seen in a vision naked on a flower. Her breasts and genitals are covered by petals, but nothing much is left to the imagination. Later she is released from the flower and floats up naked mostly seen from far away.
Morgan must be poor because she doesn't have many clothes ;) We can see her underwear beneath her loincloth during fights. Her breasts are not fully covered and her nipples are outlined at times. Her body is heavily emphasized, constantly. In fact most women in this series are soundly in the jiggly double D category, with lots of emphasis on the jiggle.
