Rubenesque has one connotation, and it's the one you're tried to use it for. It means a "full-figured" woman and came from the paintings of a certain artist who liked to paint exclusively such women.
Jamie Lee-Curtis is far from "full-figured". You. Fail. Asif. 
Raymondo, I apologize in advance, I don't want to test you on your vocabulary, but you don't know what 'connotation' means. A word does not have "one connotation," as you put it. To co-note means to note or signify
besides or
in addition to the main meaning of a term. Perhaps what you are thinking about is a word's 'denotation,' or a word's primary definition.
