4. Supergirl (Supergirl)
Despite the fact this film was made in 1984 (and despite the fact I really disliked the Christopher Reeve Superman outfit that isn't too dissimilar to this one), Supergirl's outfit was actually very good. This style certainly suits females more than it suits males and Helen Slater pulls it off incredibly well. It consists of a tight-fitting blue top with the infamous Super-logo on it, a red cape (again, we all love capes) and a cheerleader-esq skirt (and we all love a cheerleader outfit too), as well as knee high red and yellow boots. It still holds up pretty well to this day, without looking silly like the Superman alternative, and that's really saying something.
