Had to '
google' that one - so should they have been wearing cloak-like garments instead then?
Edit to add:
According to
AP1358
White nylon or cotton gloves with one button or press-stud are to be worn by:
a. RAF and PMRAFNS officers with No 1A and 6A SD, whether or not a sword is being worn, and with No 1 and 6 SD when a sword is worn.
b. WOs with No 1 and 6 SD when a sword is worn.
The WO in question does not appear to be wearing a sword.....so, correctly dressed or not?
