Fie upon you.

Starfleet miniskirts are sexier, and expose more skin, and when one of the character's sexier attributes is her green skin, that shit needs to be showed off. Red would be most flattering for her, since it'd make for the best contrast with her green skin (and compliment her red hair and lips), but sociology (or "xenopology," or whatever the future word is for her speciality) is more science. :(
