I recently got accepted to undertake an intership at a Government research facility that is affliated with my University. However, I'm not entirely sure about what to wear. I will obviously be wearing a labcoat whilst in the lab but I will also be spending time on the computer, reading papers and 'in the office' so to speak. My problem isn't so much about what is appropriate (anyone involved in the science faculty will know that pretty much anything goes as far as dress standards) but more about what I can wear without looking like I'm some sort of elitist. When I first met my supervisor he was wearing jeans and an untucked, short-sleeved button up with lots of miniature pictures of The Beatles (in multi-colour) on it. While I'm sure he would be dressed differently had there been some sort of meeting schelduled, it looked as if this was his 'standard' work outfit. Ideally, I would like to wear trousers, dress shoes, button ups with a sportcoat and the occasional tie but the last thing I want to do is make my supervisor/colleagues feel under-dressed and end up resenting me because of it. I'm a bit older than your typical intern (26) and my supervisor seems like a really nice guy but it's hard to say how he (and the other post-docs etc) would react to 'the new guy' wearing more formal clothes. Any general advise/experiences (especially from Aussies in the field) would be greatly appreciated.
