a normal woman in that dress. When she entered, I thought, OMG, is that really Kate? :o) And she rarely wears dresses, it’s usually separates.
I guess that garb they usually put her is has become somewhat of a signature for her so it may be her own personal style also. Who knows. When you constantly wear a blue streak in your hair, paint your nails neon lime green with an index finger painted a different color, I guess the ornamentation she wears isn’t really that outlandish after all.
