Another reference to the 60’s can be seen in some of the outfits, more specifically Pam’s powder-blue outfit from S1E12 and Nan’s pink and black suit from the tolerance rally in S4E9-10. Both are similar to the pink Chanel suit worn by Jackie Kennedy Onassis on November 22 1963 in Dallas. Of course, Pam’s is much closer and might be a foreshadowing of the Dallas story of season 2, but Nan’s is also relevant as she did discuss the civil rights movement of the 60’s with Bill both before and after the meeting. This is what was said before the meeting:
Bill: How can you have an event in honor of the living dead without any living dead? It’s like having a civil rights protest without any black people.
Nan: They’re called African Americans, and maybe those protests wouldn’t have turned into the bloodbaths they became if they hadn’t been there. Ever consider that?
And after the meeting Nan said:
"There are glamour squads all over Shreveport. If anything leaks…"Remember the Civil Rights movement, sweeping social change…" and "Inevitably accompanied by violence and the appearance of chaos." Yada-yada. That is the spin we’ll give it."
Jackie O. kept the bloodstained suit on during the whole of November 22, despite being offered a replacement, similar to Nan keeping her suit on. Nan’s version could even be seen as a modern variant of the original one.
