I am a mid-20s banker in the process of building up a business wardrobe. My first suit from WW Chan is a very nice light blue on navy pinstripe suit from WW Chan. For my second suit from WW Chan, I got a very subtle navy herringbone suit. Although it looks very nice I do wonder if I should have gotten a solid navy because the convention dictates that everyone must have a plain navy suit. Do you think I should be able to get by with the herringbone navy without having to add a plain navy to my wardrobe?
