^If you were a songbird in that sylvan glade you would be picked up by a hawk in about 5 seconds. However, it looks pretty good, maybe a more neutral shoe to ground the look a bit? Tan, brown, white boat shoe or driver?
Since I wash and dry all of my polos with their collars up I can't help but to want to leave the collar up when I put them on. Nonetheless I immediately fold the collar down. The media industry's version of CBD.
The fashionably short coat makes your hips look as wide as possible.
A longer coat would end at a narrower point on your frame.
The current cut (raised hem) of those jackets is always a little problematic. They probably work best either with jeans, and unbuttoned, or in a suit where the transition from the the jacket to the pants is made less obvious through the continuity of the fabric.
Wearing these jacket buttoned with off white trousers does show the hem line at the widest point of the hips, doesn't it? And this sharp emphasis on the broadest portion of the pelvis, undoes the outline of a deltoid shape of the male physique which first came to be admired when the Elgin Marbles arrived in London, in a surge of neo-classicism, and hasn't really abated since.
These shorter Jackets may have started in Japan among people in their 20's. Certainly there has been a wave of interest in de-constructing British traditional menswear there. Shinjuku was awash with it a while back. And since Brooks & J Press sell vigorously in this market, jackets with this cut may have made their way upstream from the trendier districts of Tokyo into American higher end menswear. Since the cut burlesques the very traditional full canvased and heavily padded suit, it is a look that seems to work best in ensemble with other garments which support the joke, or in a casual suit in which the raised hem is less easily seen.
