Gentlemen, I'm looking for a little advice on my wardrobe for this summer. I'm working as a summer student/intern on the trading floor of one of North America's leading banks, and I want to ensure that I am dressed more than adequately for the job, especially on the first day. I worked in another area of the bank last summer, and got to see the floor, so I know that for the most part (at least in the summer) suits are not worn, and jackets are worn frequently, but end up on the backs of chairs anyways. I've got a decent amount of work clothes already- selection of dress shirts, pants, a navy blazer and grey sportcoat. I've got a few new things in mind, and wanted to run them by some informed individuals such as yourselves. A black blazer/odd jacket? I wouldn't wear a black suit to work, but I think that a black jacket would be useful and could be worn with all shades of grey pants as well as chinos. Would this be a good idea, or would it look like I had just taken a jacket from my suit and decided to wear it with different pants? Could I get gold blazer buttons on this jacket to make it clear that it's a blazer despite its being black? Shoes- I've never really known what dress shoes are best. I'm thinking I'll get some classic black oxfords with detailing on them to wear with grey and black trousers, and a pair of brown or oxblood slip ons for beige and navy trousers. Can I wear brown or oxblood shoes with grey pants? What are some good work wardrobe staples I should look for? And lastly, could someone advise me on this proposed first day outfit? Black oxfords, medium grey trousers, black jacket/blazer, french blue shirt (maybe with french cuffs, but I don't want to overdue it -I am just an intern), and a solid purple tie. Thank you very much for any help. I hope that I am able to contribute to these forums rather than simply beg for advice -perhaps a discussion on madras pants is going on.
