I have to agree with you regarding Hillary - pant suits do work best for her - I think the reason we all made fun of that was because it appears she wore the SAME pantsuit for days/weeks/months on end... ;^)
You’re right, it did seem as though the same suit was worn days on end. She probably had a closet full of the same/similar suit, kind of like men and suits. I like it when she adds a feminine touch to her Mao suits...softens the effect.
I agree that pantsuits work for Hillary and they cover figure faults. I’ve seen some on her that I really liked, some not so much. I think she has a lot of “lookalike” pantsuits, which has led to the impression that she is wearing the same one for days and days. I notice that lately she wears more colors.
As a huge "fashion don't" myself, I'm sure if I found one style which made me look nice and professional, I'd cling to it for the rest of my life. It would be terribly hard to experiment or take risks knowing that I was on the verge of being photographed every moment.
