I work in a office and the standard dress code for men seems to be trousers and shirt.
To me, trousers and shirt on its own is a look which I don't like. I always feel like something is missing when I wear trousers and a shirt.
The problem is I'm on the phone a lot so will it look odd if I start rocking up at work in a suit, not taking the jacket off and making calls?
Put on a sweater?
If every other male in the office is wearing a shirt and trousers, and you show up in a suit, it will look odd. You will be inviting attention to yourself and your dress in a way that most people will not understand. If you can stand it, you are welcome to do it, but you will likely become known as "that guy who wears a suit."
Better to work on things like fit and style within the context of the parameters of the dress code, rather than try to redefine the dress code on your own.
