Sartoria Corcos, a very florentine cut. I guess it looks unbalanced if you compare it to very different styles, but I think it does what really good tailoring should always be about: it flatters the wearer. The low buttoning creates a nice V-shape, which is a quite masculine trait. The shoulders are actually probably quite soft (though a bit extended). I think the "strong shoulders" are indeed his own shoulders. The cut away quarters are more about personal taste I guess, but I like them. In general I'd say the proportions of everything in this outfit is excellent, which is why I thought I'd share it. In the end it all comes down to differences in taste though.
The Florentine cut is one of those #menswear things. I think I love it when I see it done well, but I am a little self conscious in the one SC I have that is based on the cut with the aggressive cutaway in the quarters. I think part of it is b/c I am tall and always self conscious about looking like the jacket is too short. From what I have seen, Corcos does great work and would be my pick if I were to ever travel there or he started coming to NYC, assuming his pricing hasn't crept up to Liverano's (although I just heard some ridiculous thing like the stopped taking new clients through 2017, so maybe his pricing has room creep up there). All that said, those photos, to my eye, may not be the best representation as the jacket looks too tight and doesn't allow the lapels to create a soft, gentle kiss with lapel roll )(, more of a ><.
