Most of us men are not interested in their appearance favoring comfort aesthetics and good taste.
It makes sense in 2015 to talk about rules on how you should wear a shirt? for me, although in the past 20 years (it was much more formal and attentive) World turned and certainly not just in men's fashion, there are rules of conduct that everyone should know senonaltro.
1- The cuffs of the shirt brought in formal means (you can safely roll in his spare time) must be locked.
2- tie is a must, if you want to be elegant, a bit like the napkin at the table, one can not do without.
3- shirt short sleeve (if you like it) is allowed only in free time or on vacation, prohibited in the office under the dress or jacket.
4- the pocket in the shirt is also permissible if the traditionalists flunk him inexorably can be useful from a purely aesthetic point of view is irrelevant.
5- initial it, no initials, what to do? is considered by many vain embroider them on your shirt, personally I consider it even more legitimate because it should never be placed in positions too flashy, is fine a few inches to the left at the navel.
Perhaps not of interest to anyone but in a busy world where everything is being proposed is already packaged and ready-mix, have its own style that harks back to the canons of our fathers I believe it can still have a sense.
