Which item is not part of the No.2 Service Dress uniform?

The No.2 Service Dress uniform in the RAF has specific components designed to create a formal and standardized appearance. One of the defining features of this uniform is its emphasis on a smart and polished look. The tie, brassard, and Wedgewood blue shirt are all integral parts of the No.2 Service Dress uniform, contributing to its formal presentation.

The tie is a traditional aspect of the uniform, providing a professional and neat finish. The brassard, often worn on the arm, signifies rank or special duties, further enhancing the uniform's function and identity within the service framework. The Wedgewood blue shirt, with its color and style, is specifically designed to complement the uniform's overall aesthetic.

In contrast, the sweater is not a standard component of the No.2 Service Dress uniform. While sweaters may be worn in certain situations or as part of other RAF uniforms, they do not form part of the essential attire for the No.2 Service Dress. This distinction is crucial for maintaining uniformity and adherence to the dress code established by the RAF.
