HK Support team for the Korean Horseback Archery Competition

I have max. 5 sets of costumes for the supporters of the HK team. They are in Ming military style and are bright yellow. (Yellow tabard and side skirts.) They just slip over normal clothing. No particular size.

I hope that our team will wear black basic clothing. Black kung-fu pants and long sleeve black T-shirts would be good. Also black or brown shoes/boots and no sneakers (unless plain black).

I will discuss separately with the team members.

Any ideas for headgear?
