During your first week of training at NSI, you will purchase all required uniforms. Until your uniform fitting and issue, Officer Candidates will wear official Navy Physical Training (PT) gear as the Uniform of the Day. Do not purchase uniform items prior to arrival. Uniform specifications are precise, and buying from unauthorized sources may result in unnecessary costs. If you already own uniform items that are standard for both officer and enlisted personnel—such as an all-weather coat, Navy-issued PT gear, black leather gloves, ribbons, medals, or warfare devices—bring them with you. Former Chiefs are also required to bring all khaki uniform components. However, if the Class Officer or Senior Enlisted Class team determines these items are unserviceable, you will need to purchase replacements. The typical Uniform of the Day at NSI is Service Khakis.
All Officer Candidates, except prior Chief Petty Officers, will receive a one-time uniform allowance to cover the cost of the initial uniform issue. For additional details regarding uniform allowances, please refer to the link below: DoD 7000.14-R Clothing Monetary Allowances (Refer to Volume 7A, Chapter 29 - Clothing Monetary Allowances).
