What items are included in the No.2 (Full) Service Dress, excluding belt, socks, and shoes?

The inclusion of items in the No.2 (Full) Service Dress is specifically aligned with the official dress regulations of the RAF. The correct choice encompasses the appropriate items that represent the proper uniform attire for corporals.

The beret is a recognized headgear for RAF personnel, and the Wedgewood Blue shirt is the standard designated shirt worn as part of the service dress. The tie complements this shirt, and the jumper adds to the uniform's formality and comfort. The brassard is an essential part of the uniform as it often indicates the role or position held by a service member. Finally, blue trousers or skirt are the designated lower attire, ensuring the uniform maintains its characteristic color scheme and appearance.

The other options contain discrepancies regarding the designated shirt colors, types of ties, or associated lower garments that do not align with the established service dress requirements. This makes the first option the only one that accurately reflects what is included in the No.2 (Full) Service Dress.
