Yep, I mistook Clark's sport jacket for a short topcoat on the stand-in for that reason. This outfit screams Birthright Clark in my opinion. Speaking of which, I like how they have opted for more of a business casual as opposed to business formal look for Clark. As far as I know, unless they are covering the White House or something, print journalists don't really wear suits to the office anymore, which also explains the reversal of the Superman/Clark hairstyles. It wouldn't make sense for casual Clark to wear his hair slicked back. I think Birthright did that as well - having Superman's hair slicked back and Clark's more loose and natural in contrast.
Anyone else love all of the country/farmboy influences in Clark's fashion taste? The bulky shoes, heavy brown sportcoat, thick leather belt, and fondness for plaid button-down shirts all evoke a bit of country rusticness. I also don't think it is a coincidence that Clark's clothes seem to favour warm, earth tones like greens, browns, and tans. (Even the grey dress pants Cavill was wearing in the charity photo were a warmer, earthier grey) Wilkinson is damn good as what he does.
