Around in the 80's, I was told I looked like Jane Fonda. Then later on, somebody said I reminded them of Barbara Feldon (Agent 99 on "Get Smart." ) I don't see the ressemblance (or the ressemblance between the two of them!
But people do sometimes see ressemblances where there aren't any. I travelled to London with an aquaintance, and first, a shop keeper asked if we were sisters (maybe just chit chatting). Then, some guy in the group we were with asked if we were twins. VERY bizarre as I am about 3 inches taller, she's blond (dyed) and I'm brunette (with some grey now), and neither of us see the ressemblance (but we were both flattered because we each think the other one is cute,LOL!) Maybe because we both have two eyes, a nose and some hair??
