The 42S washington fits me pretty well off the rack. We can compare measurements if you like. I wear a 16.5 neck/ 32 shirt, 42.5 inch chest, 33.5 waist, I'm 5'9 but my inseam is only 29ish, shoulders around 18.5/19. My only complaint is the button stance is a tad high for my proportions. If you have the same inseam or longer than me(since you are 5'6), it might be better for you however, however.
