I used to do a full suit. Then it went to Kakies (Think that's it) and a Polo. Now its down to jeans a Punisher T - Shirt and etnies... Yep I have gone full blown IT GUY.
I still rock nice clothes when I need to I just find myself wanting to be more comfortable at work. Plus that sometimes I am working on cabinets with switches and routers that don't get touched for years and that gets really dirty.
