I have an interview tomorrow with an i-bank in London. My black suit which was suppose to arrive today didn't. So I have a blue blazer which I plan on wearing with a pair of light grey khakis, but I don't know what to wear under it. I have a nice white Ralph Lauren shirt, a dark blue stripe Ralph Lauren shirt, a Ralph Lauren yellow tie with dark blue stripes, and a Ralph Lauren yellow v-neck sweater. Can you tell I like Ralph Lauren?? Anyways, I need to pull off the American preppy look I think. I was thinking of wearing the white shirt with the tie and the sweater on top with the blazer, but do you guys think I should just go with the blue stripe shirt with the tie and blazer? Any other suggestions would be great. Thanks guys. I wouldn't normally worry, but this is i-banking where if you have a hair coming out of your chin you might not get the job.
