I'll throw in my two pieces of copper on this, mainly with what I think is missing from the posts. First off I think everyone forgot what should be the numero uno on the list, and that is a well rounded, personal fashion sense. I think from there everything else follows suite for you may have all the items listed and more, but if you don't know what works for you then you're still not "fashionable", just trendy. I agree with GQ Lawyer that it's those little details that go a long way. As to the other items I see missing, in no particular order, one is your favorite vintage T-shirt. If you know how to work it then it screams style, but in that relaxed, "I don't give a damn" sort of way, think James Dean or all the other standards people mention for their cool. Another is good underwear, keeps you comfy, everything in its proper place, and women can tell a lot about a man by such details as this too. Another item I think a man needs is a day-planner, or pda. In some circles it may fashionable to be late, but many people see it as just sloppy and irresponsible on most other occasions, besides why even be dressed to the T if you don't even know what event you're dressing for. What I also feel goes along with said day-planner that exudes refinement, but may not be so necessary to be on the list, is a good pen. I think also what needs to get a mention is also a good tailor/cleaner for you may leave a store with style, but she/he keeps your clothes in good shape so you can be stylish every day.
