I never really understood this thing about Web Hubble when she clearly has Bill’s nose and I can see the chin in her mother.
Aside from that, I won’t voice any judgments on her appearance since if I can’t say anything nice...
I guess it’s the lower lip. Chelsea’s grandmother, Virginia Clinton Kelley, was no great beauty either, and you can see facial similarities between young Chelsea and young Virginia, but nobody wants to let go of the Hubble thing.
