I got into this discussion with one of the neighborhood girls (about 7 y.o.)

Her: "Why are you wearing a skirt?"
Me: It's not a skirt, skirts are for girls. This is a kilt.
Her: What's the difference?
Me: How do you put a skirt on
Her: (Pantomimes pulling a skirt on)
Me: When I put on my kilt, I wrap it around me and fasten it (Not always true, but she didn't need to know that).
Her: My mom has skirts that she puts on like that.
Me: Why is your mom wearing kilts? Kilts are for boys.
