The lass may or may not know what a kilt is. I have been asked similar questions, and rather than get upset, or take it as degrading, I prefer to politely answer the question. " This is a custom made kilt sewn by Rocky at USA Kilts of Phoenixville, Pennsylvania. The tartan is MacNeil, thank you for asking." or similar description of the garment and the vendor I purchased it from. Usually, I get a slight stammer if they actually meant kilt and said skirt, or why is it called a kilt? I have had many conversations that have taken the skirt to an educational opportunity for the person asking. The other plus is that by answering in this manner, the ones that think they are belittling you, are instead finding themselves belittled by their own actions. I even try this on the well intoxicated crowd that are on the trains after closing time, with very good success.
