Cora wears national Izhorian costume in the Karelian Isthmus
Cora is not relevant to Izhorians. It's me who was born in Saint Petersbourg, and I decided to learn who had lived on this land before Slavs came here and then many years ago the fortress was built. So... yes, these people. Just look how the dress suits Cora and she's pleased as the costume looks fine and she feels comfortable wearing it.
