5. The Fantastic Four (Fantastic Four Movies)
The Fantastic Four costumes are horrible. With all the glamour of a cheap one-piece tracksuit, the blue body suits that the cosmic-powered quartet wear are simply awful. As unflattering as they are dull, the only thing that these things have going for them is the fact that the molecules that they are composed of were also altered in the cosmic storm that granted the team their powers, allowing the fabric to conform with the wearer's form and to not succumb to the wearer's powers (so, for example, when Reed stretches, so does his suit, when Johnny is engulfed in flames, his suit doesn't burn off and when Sue turns invisible, her suit does too). Still, it doesn't compensate for the fact that they are hideously dull and highly uncool.
