I want to know the answer to the following question:
When was the current USAF dress uniform standardized?
All the background I'm provided with is that "USAF personnel assigned to Base Honor Guard duties wear, for certain occasions, a modified version of the standard service dress uniform, but with silver trim on the sleeves and trousers, with the addition of a ceremonial belt (if necessary), wheel cap with silver trim and Hap Arnold Device, and a silver aiguillette placed on the left shoulder seam and all devices and accoutrement.". Is that enough to answer the question?
Answer: no
