I am inclined to wear a suit as all of my female friends think I look pretty good in a suit. However, there is a chance that the suit selection is limited - the trousers might no longer suit my waistline with one outfit, another outfit could still be covered with detritus from that last wedding and so on. Also sometimes you don't want to advertise to the world that you are going to a job interview. Therefore the suit idea just might not be possible. Next choice, out of the regular work wardrobe, is to wear the clothes I am happiest wearing. These are the ones that are a bit like a wrap-around comfort blanket. For me, most important is to actually be clean. I couch-surfed my way to one interview some years ago, where there was a problem with the water. I could not shower or even do a minimal effort wash. I felt horrible and I did not get the job. One idea though, if you work primarily with one programming language/application/framework, then, if you have any merchandise - e.g. a hat or a T-shirt emblazoned with the language/app/framework logo - then that could work and break the ice.
