I have been looking at the s isaia chalkstripe selling on b and s and I'll go check it out at my local NM one day thanks antirabbit.
Do, I need to fly out there and drag you to NM to try it on?
Seriously, I am built a bit like you, and I can say that nothing fits me OTR like the Isaia base S. You will not be anything but shocked at what it will do for you. I think part of it has to do with the slimness of the sleeves, and also how there is a contour to the back that makes a mans profile look great. Im not sure it would look so good on a very skinny or shapeless body. You have to have a chest and shoulders to make this cut really work well.
