When my son was five years old, we bought him a kilt which matched mine. He would only wear it when I was wearing mine. I do not recall anyone ever making fun of him. But, it needs to be said that when he outgrew it, he decided, most emphatically, that he did not want another kilt -- unless it was a camo one -- and I had one to match. We don't have matching camo kilts - yet (he's fourteen now) but I still think about it...
