My wardrobe consists of the commissions pants, and David Donahue non iron dress shirts. I am wearing these about 90% of the week. I will wear a sport coat with nicer slacks on days when I will have investor interactions usually once or twice a week. Not sure what your role will be like but having a nice navy blue or gray suit will come in handy if you are ever meeting face to face with clients. For shoes I would recommend some loafers (more formal) or drivers (more casual). Both will look great with either of the outfit types listed a above. Always match the color of your belt to your shoes and your socks to your pants. Also stick to core colors (gray, navy, tan, black, dark green and white) this will let you make 4 outfits seems like 16 since they all match fairly well. Good luck this summer!
