Logical reason why the Star Sapphires’ outfits are so revealing: It entices men. Their outfits are deliberately made this way in order to psychologically manipulate men, so that they can be crystallized once their guards are down.
However, it’s illogical to assume that all male sentients find their outfits attractive. Of all the potential variation in sentient life, it’s biased to think they share the same tastes. (Even Razer, who is very humanoid, seemed resistant, and that’s probably just his culture influencing him) Thus, that they have such revealing outfits subtly indicates their misandric belief that all men are the same. (in this case, in what men find attractive)
Logical reason why Razer was immune/resistant to Queen Aga’po’s wiles: In his culture, (judging by Ilana) women wear very modest clothing. It’s possible Razer has never even seen his wife in lingerie.
Reason why Carol Ferris has long hair as a Star Sapphire: Women tend to have longer hair than men. (at least in Western cultures) Furthermore, men often go bald, but baldness is rare among women. The extreme opposite of the male trait of a bald head/balding hair is long, luscious hair.
I find it peculiar that Galea and the Zamarons all have belly buttons. Does that mean they all have mammal-like embryonic development? Not necessarily. Birds have belly buttons too, though it becomes more compact as they mature. Their belly buttons also look much like a scar, rather than an indentation. (as it usually is in humans) One source claims alligators have a belly button, but it does not seem likely since it cannot be corroborated. (and the same site claims crocodiles do not have belly buttons—-why would that be so? It is implausible.) I wondered why Kilowog would love Galea if Galea was not also hatched from an egg, as he was. However, I now realize that this does not matter to Kilowog. How often do people look at the belly buttons of those they love? Probably not often. (If they look down at all, it’s probably not that far down.) In addition, why should Galea’s embryonic origin matter to Kilowog when Razer loves Aya though she’s not even an organic being? (in the sense of having organs and/or being carbon-based. She is still alive.)

As a design reason for having belly buttons, it’s from the comics. (See http://www.tumblr.com/tagged/zamarons?before=1347115295) (It was difficult to find a picture of a Zamaron with a belly button. In the comics they wear garments which cover the belly button.)
As another design reason, it’s considered appropriate for females to wear garments that expose the belly button, but considered inappropriate for males to do the same. Furthermore, judging by the Wikipedia article, much more attention is given to the navels of women. The greater attention given to the navels of women might make it an indirect feminine trait.
I wonder if the Cephalon is sentient. Would the “becalming ray” of a Star Sapphire work on the Cephalon if it was not? ….or maybe, to its primitive animal brain, the “becalming ray” of a Star Sapphire is percieved as something more visceral than the love of sentients. In which case, of course it is the ally of the Star Sapphires—-if it comes floating in when summoned, it receives fulfillment for a primal desire. (The Zamarons might even understand this, since apparently they do produce offspring. Aga’po has a niece.)
Unlike the other Star Sapphires, Galea’s outfit does not have high heels. Heels would probably break under Galea’s greater weight. (if her comparative bulk is any indication of her weight)
While Razer is initially upset by the revelation that Aya based her appearance off Ilana, he seems to quickly get over it. He trusts Aya, even if he believes she’s a machine at this point.
