How to Crease a Navy Cracker Jack Uniform

The Navy "Cracker Jack" uniform consists of a jumper with a yoke and trousers. These uniforms are formally known as Service Dress Blue and Full Dress Blue, and are worn by male sailors at pay grades E-6 and below. The jumper may be creased, and creases in the back flap of the jumper are customary. Neglecting to care for one's uniform can be cause for disciplinary action. Knowing how to press your uniform correctly will help you consistently meet Navy uniform standards, a small but important part of your military career.

Launder and dry the jumper according to the directions on the label, which is sewn to the inside of the jumper.

Spray the jumper with water until slightly damp. Iron the jumper to remove wrinkles. Use the iron setting appropriate for the fabric. For the Service Dress Blue, use the wool setting.

Lay the back flap of the jumper inside out on the ironing board. Divide the back flap into three equal parts. Fold the leftmost third of the flap in. Press the fold from the top of the back flap through the trim. Repeat with the rightmost third.

Find the centre of the shoulder seam on the front of the jumper. Fold the front of the jumper from the centre of the shoulder seam to the hem, making sure to avoid folding the back. Press the fold from the centre of the shoulder seam to the hem of the jumper. Repeat with the other shoulder. These front creases are optional. Iron the trousers without creases.


Uniform fabric can change throughout your military career. Check the labels of each new uniform for care instructions. If the uniform fabric is a blend, such as a wool-polyester blend, use the lower of the iron settings. Creases are not authorised for the trousers for the Service Dress Blue and Full Dress Blue uniforms.


Sewn in creases are prohibited.
