The USAF Tartan kilt isn't part of any official air force uniform, so you wouldn't be violating any uniform laws. The medals are yours to wear. I don't know that I'd wear 'em on base. I might suggest the Blue Doublet with Gold trim that the USAFR pipe band wears. I'm asking the honor guard to buy mine. Do you play pipes? Maybe pulling honor guard enough would get the base to buy you 'proper attire.'
