Wardrobe Continuity
Anyone else a little distracted by the fact that they all wear about three outfits over and over? I assume it has to do with the way they write and shoot a full season at once, but it makes me laugh to see someone like Carol, who you think would be a total clothes horse, wearing the same dress and the same blouse and pants in almost every episode.
Plus, there are times where their outfits change in the course of a day for no reason. So again, I assume it has to do with shooting dates.
Anyway, I didn't mean to notice it, but once I did it was hard to unnoticed it. Continuity thing.
