WCIF late 70's early 80's style dress (see picture)

I'm having trouble finding exactly the style of dress that I want for one of my Sims (mainly because I'm not sure what the style is called). The picture is from a JC Penney or Sears catalog I found from 1980 (I'm not sure which), and comes close (what I was looking for was from an old Colgate toothpaste commercial, but I can't find the commercial, darn it!) The one that comes closest is the one on the right (the yellow dress, though hopefully, I can find it in different swatches, of course!) Anyone know what I mean? All I know is that this style was in the late 1970's and early 1980's.
