I guess I'm an outsider here. From what I've seen of Katie in the past, IMO, she usually lacks style and looks like she doesn't put much thought into coordinating her outfits, sometimes appearing sloppy. Often I have to ask why she wore this with that?
The only thing I don't like are the jeans and sunglasses. The coat, sweater, shoes, and handbag are nice, but...
gray is not her color and I wouldn't wear it with the top and jeans. She'd look much better in darker slim leg full length jeans with the dark top she chose. A navy blue coat would pull this outfit together.
I realize ankle length jeans and holes are the trend, but they make her look sloppy. Since her ankles are showing, she should have socks on if the weather is cool enough to wear a coat.
Those sunglasses are not flattering on her. A slouchy shoulderbag would look much better.
I think her outfit would pass on a college campus, but she's 41 years old and a celebrity.
