Do Normals tend to lose the white on their sides?

Patterns don't change, but as she gets older, some of that white may be harder to see, simply because she's going to be bigger and rounder and her body will cover them up.

Sorry, I think that's more along the lines of what I meant. The question should've been, "Will the white be harder to find?" and the answer seems to be here. Thanks!
