C vs G: what's the line between being petite irl and having a petite Kibbe? Where does the balance end and smallness become the main focus?

I'm thinking about recent celebrity discussions, but I'd also like to speak in general terms, for those of you who are confused between gamine and classic.

Lately, we've been talking about celebrities who seem classic—in essence, roles, proportions, etc.—but are very petite, short, and narrow. How important is being petite in real life, always being smaller than everyone else? Is it a characteristic that prevails over all others and should make someone lean toward gamine rather than classic?

(And no, sometimes the sketch seems to show both. If it can't do that, please explain how)
