There are so many contributing factors to the ugliness of the 1979 Starfleet uniforms that it’s kind of miraculous. They’re like the holy grail of bad fashion. In terms of colour, the problem is immediately obvious the first time you get distracted by a background extra who looks naked because they’re wearing a skin-coloured body suit. Although of course, wearing flesh-tone clothes is already kind of an aesthetic disaster. For those of you who always feel guiltily puzzled when someone describes two colours as “clashing”: it’s similar to the Uncanny Valley. The closer two colours get to each other, the more uncomfortable they are to look at. This is doubly true for clothes that match your skin-tone, because one of the colours that looks gross is you. — Star Trek: The Motion Picture — A costume design nightmare.
