Dancing Scarves are light armor that provide 0 AC bonus when standing still and +2 AC when moved more than 10 ft in given round.
Can you use the feat Armor Focus and focus on these scarves for constant 1 AC bonus and additional conditional 2 AC (so if you're moving every round you get +3 AC).
That is not an accurate representation of what Varisian Dancing Scarves do. They don't provide a +0 armor bonus, they explicitly "provide no benefit while you are standing still."If it said +0 armor bonus with an additional +2 while moving I would say it works. But it doesn't.
