I'm trying to apply all what I've learned into casual style. I'm already well ahead of the curve with regards to business dress and whatnot, but I'm completely lost when it comes to dressing for the street. I was thinking about going for that rumpled dress shirt + sweater + jeans + jacket thing. It sounds and looks a lot better than my current "wear whatever is clean" method. To the guys who do something similar to this, and have experience: How long do you prefer your shirts to be, to look their best untucked? Any pitfalls I need to be aware of?
