The redhead(Crystal) normally is busty with pink hair (use to be longer).
Honey (The white-haired girl normally has a more normal figure, but still has long hair).
There's a whole story explaining it on SailorSun.org. But basically, Crystal is a siren with a hypnotic voice and exaggerated figured (which is a norm for sirens). This is what if Honey has Crystal's siren powers.
I do like girls with pink hair! ^^' Though, Crystal has VERY PALE pink hair there. I think I find blonde Honey more attractive then white haired Honey. XD
As established in the comic, the Siren Powers are what cause the exotic hair and generous curves. That's why Crystal is now a flat as a board redhead, rather than a busty pinkette.
