I think she's always well dressed and very chic.usually just a silent reader and just follow her because we are the same age and I find her life so bizarre in comparison and in some ways like a middle-aged women (well I feel younger than her even though my partner are also planning house,wedding and children) and I randomly thought,seeing her in a bikini, that she must be pregnant. Glad I am not the only one,haha
Her style is modern day classic/ traditional (if that's a thing!) Not trendy, which isn't bad.
I'd imagine she's always had an older head on shoulders, her style suits her personality.
