Note: The style of pants— Can tuck any nice shirt under it. Tuck casual shirt and wear blazer. The shoes— They look comfortable, wearable to work. It could be done with flats as well, not to as potent an effect I think. The strap on the shoes are the most important part.
This could be a great look for fall. I like mock turtlenecks and my waistline can be an asset. I like the tailored, sophisticated look, but it has a little edge. I need to probably buy my own shoes, but I like oxfords.
