Mysterious Fashion Statement?

[strange1]

Hi,

There was an episode in which one of the girls was visiting a college, and ended up talking to a student in one of the dorms (yeah, it's vague; it was a long time ago). Anyway, the student in the dorm room was wearing a relatively plain, plaid button down shirt (as was the fashion back then), but backwards. The director seemed to linger on a shot from behind the student (pointing out of the room towards the door), clearly showing the row of buttons running down her back.

Was that just something goofy, or was that the trend at that time (if it was, I don't remember), or was it some sort of mysterious fashion or political statement with alterior motives?

Can anyone point me to the name of this episode and/or preferrably some vidcaps?

Thanks,
Strange1
