CUFFS. There is a lot more going on with suits that you may ordinarily think. Over the years a good number of Army Colonels asked me what I would recommend they were for job interviews when getting out of the military. The first thing I would tell them is read John Malloy's book Dress for Success. Next I would say know your interviewer and company. A pink button down dress shirt looks real good in Boston but in NY or DC you would get run out of town. In the Pentagon blue button down is the way to go unless you are SECDEF then white is it but you will change it every day. Buying a suit at Brooks brothers, Nordstrom, and Lord & Taylor is most often a good choice but make sure it is tailored for you. A good suit not fitting well looks bad. The Wall Street boys are an experience out of the main stream. They make so much money they have a pissing contest to show each other up. If you work there you will be buying that line of clothes. Good, bad, or indifferent that is the culture. Lastly, president Lincoln was shot and buried in a Brookes Brothers suit and Pink shirts get you laid according to Dress for Success. Go figure.
