In general, I'm a great fan of pairing a silk blouse under a suit, even one with some sheen to it, like this one. But I think Ms. Jackson has a combination of wardrobe factors going on here that have conspired to create a look that is pretty, but perhaps not as professional as it could be. As I said, shiny silk is fine. A little bit of ruffle is fine. Together, probably still ok for the office, but not on the day you're giving a press conference.
There is a similar situation with her jewelry. Big hoop earrings (of good quality) are fine. A stylized cross is fine, on a rope instead of a chain, probably also acceptable at work, but not on camera.
Ms. Jackson has a great hairstyle. Very short looks can be work to maintain in terms of the frequency of the cut, especially when keeping your look consistent is important. In this video, I would guess that it was just cut, within a week or so, and probably looked even better a week or two after this. But short cuts can be great on women with straight hair and fuller faces. The very short bangs help keep this style looking current and youthful.
We know grooming is important, but there is such a thing as an over groomed eyebrow. Ms. Jackson might do well to back off the tweezers a little here and maybe even add some brow powder to her makeup bag.
