Wearing a suit to work...
I also work in southern California and regularly wear a suit to work. I would say wearing a suit to work depends on the industry.
In my opinion the idea of being in a suit to work is rather old fashioned. Well I agree to the fact that a suit is the perfect tool to give a positive first impression to your interviewers, bosses or even workmates but trust me this is slowly fadding away. Someone earlier on just mentioned that if you went to a LinkedIn, Google or Apple interview the guys would just be left laughing behind.
All in all it depends with the profession you are in. Too bad the sales guy in most cases have no better option.
Just a quick comment from the other side of the pond..London ,England to be more precise.
Over here you better not even turn up for an interview without a suit you are doomed from the second you walk into the room.This includes places like LinkedIn,Amazon,Google..Basically the rule of the thumb is ALWAYS wear a suit unless stated othervise.Once you get the job the dress code is up to the company(corporate,smart casual or jeans an polo shirt)
