Probably 90% will know who Jeanette is, but the will probably refer to her as "that asian chick". Very few if any will know who Alison, Karen or Ga Young are. Unlike you though, most people here know Karen's last name and it isn't (?).
Yes, it is true that Jeanette has sex appeal and the public recognizes it, but she also has done well with her personal branding (i.e. the black leather outfits and her nickname "The Black Widow").
Of course the guys won't generate a crowd with a low neckline, but turn the tables. Ask how many women from the WNBA the average person could name. Not many if any I presume.
Exposure good, burning bridges bad.
