Transitioning from a long career, or even just a few years, in the military to a civilian job can be a culture shock for many people. One area which may present some challenges is workplace attire. There may be questions and concerns for veterans, especially those who have spent a career of 20 years in a uniform every day.
Depending on the work environment, especially in the defense industry, guidelines are available on many contracting firm websites.

Generally, a helpdesk or IT employee will dress far more casually than a program manager or analyst.
