a lot of it will depend on who you work with, the company you work for, and whether or not you are client facing.
i'm a code monkey myself and while my company would have no problems with it my current clients wouldn't either, my direct team lead is a little closed minded and has caused problems for people she has issues with in the past, (lgbt person) and because it was all kept within the legal guidelines of the company, they could do nothing about it.
i know of other clients in my company that would have serious problems if they found out how i dress under my jeans.
so really it's a really clear "it depends"
