Rep. Louise Slaughter spoke on the House floor about trade with China this week. She wore a Red Jacket:
This shade of red is good for the Congresswoman. It's the shape of this jacket that's problematic. The huge lapels and boxy shape make her torso look expansive. Even buttoning the jacket would pull in the silhouette a bit more and improve the look.
Although we don't see her in profile in this clip, I bet she would benefit from a more supportive bra as well. Wearing a bra that is the wrong size or not supportive enough or stretched out can lead you to buy blouses and jackets in a larger size than would otherwise be necessary, leaving you with lots of extra fabric around the waist and sleeve areas. It looks like that might be what's happening here.
