The necks look too long because you'll notice everyone is wearing giga massive collars or whatever around their necks since the base outfits are designed to be scifi. Since the bikini and other revealing outfits don't adjust the skeleton, the stretched out necks remain the same. It's the same thing how whenever you wear power armor in Fallout 4, what's happening underneath is that the player model's limbs get stretched out to accomodate the PA skeleton.
