So I'm a junior in college and I have a few interviews set up next week for internships at banks. I'm pretty strapped with cash and already have a suit from Zara which I've tailored a bit to fit well (yeah I know, but whatever I'm broke ) and dress shoes (cap-toe oxfords that cost more than my suit) which I'll be wearing. Basically my question is regarding the choice of shirt and tie: I know banking is a pretty conservative industry so I was thinking a light blue button up shirt (I already have a nice light blue and a nice plain white) and I'm torn on a color for my tie. Any suggestions on colors and brands that won't run me anymore than ~$50? Probably will be heading to the mall in a few hours so any suggestions are appreciated.
