Agree @BunsenBurner - the pinks and oranges are stark and have to be just perfect to look good IMO. These blues and greens really bring our her eyes and looks professional yet soft an approachable at the same time. Here I am noticing the jackets because I really like them but most people probably just take in the whole impression and see her rather than the jacket (in contrast to that yellow jacket from the last campaign). I am still not a fan of the super electric blue, though.
She is “doing” (as Stacy London would say) a lot of that car coat length which I think works well, particularly for both speaking at a lectern and moving around on campaign stops. It just eliminates a whole category of things to worry about.
