Monogrammed shirts for Analysts

some may disagree with this, but i believe that monograms are fine no matter your rank. however, i notice that the occasional distaste for people that have monogrammed shirts tends to stem from the fact that the monograms are located in a very prominent area so that it actually looks tacky or ostentatious (when in fact, dress shirts had long been considered underwear until the pre-world war II era, so the thought of a monogram as an apparent means to "show off" seems rather ridiculous if you think about it).

in my view, if you're going to have a monogram, keep it simple and discreet. usually people will have it centered on the welt of the pocket assuming there is one; otherwise, have it just a few inches from the shirt's placket or above the waistline. i guess the poinit of it all is that a monogram is a nice touch, but i don't think it is something that should be used to deliberately draw a viewer's attention. subtlety is the key

Or how about don't have 1

I wear them because I get my shirts custom made.  This is definitely the cheaper route than off-the-rack shirts, which you must get modified.  As numi said, just make sure they are subtle (ie. same color of the shirt)
