I just got a promotion and I'm being moved to the London office of the company I work for. I'm not nervous about the job, but I am nervous about being underdressed. I'm a 25 year old woman. Usually I wear jeans and a t-shirt to the office, with a cardigan if it's cold, but I worry that I'll stand out as being underdressed.
For some context, it's a big law firm and I am not a lawyer.
