It may be a simple garment to wear, and being commited to a specific tartan makes a persons color options simpler for the rest of the wardrobe, but for me it's still the raw masculinity of the kilt. Even when someone wants to try to call it a "skirt" it takes a healthy masculine ego to stand tall and stare them down or ignore them outright. Now that I think on it, maybe the functional simplicity adds to that masculinity. Masculine things like tools and vehicles are frequently simple, solid, and functional.
