Yes, one of several things I don't understand about this Twitter exchange is that, although I've often heard/seen CT say that she wears make-up (or at least eye make-up) all the time, I've never heard her 'express insecurity about her appearance'. Couldn't it just be the way she prefers to look?
In the days when SH used to say that she only ever wore high-heels, were we to have understood that it was because she was insecure about her height/leg length - rather than that it was simply the way she preferred to look?
