Yeah, go with the saffron-- kilts aren't part of the Irish national psyche, so don't be too suprised if most people you meet think you're a little daft. Generally the Irish are pretty tolerant and you shouldn't get punched out too often. Just kidding about that last part. Most people will think you are a refugee from an Irish pipe band.
