Which is an important distinction, because sometimes the show-runners do decide that. In example of one where I think it improves it, in Youjo Senki, the military uniforms in the anime are... uniform, male and female. While in the manga, while not fanservicey, the female uniforms are clearly cut differently than the male ones and follow the bodyform rather than being blocky.
Probably the manga-runners made that decision.
