Incorporating a feather?

My home LARP is always evolving and the new Race packs came out the other day. (3 days b4 the next event...) and i need to have a ravens feather on me at all times. (Tribe business)

I cant think of where i could add a random feather. I play as Norseman, my kit is done based off real norse and its pretty "filled out" already. I feel like popping a feather just anywhere would look weird. Do you folks have any ideas please?

Oh and I cant wear it in my hair cause i have a helmet. Thx!
