A kilt is defined as a specific type based on its materials, construction, design features, and intended use, with each category—such as traditional, utility, hybrid, or contemporary—sharing a consistent set of characteristics. Key factors include the fabric used (such as wool tartan or modern durable materials), the method of construction (including pleating style and structure), and the presence of functional or stylistic elements like pockets, closures, or mixed materials. While all kilts share a similar overall shape with a flat front and pleated back, it is these combined attributes that determine how a kilt is classified and how it is intended to be worn.
