Fabric weight affects how a kilt feels, moves, and hangs, influencing comfort, structure, and overall appearance. Heavier fabrics create a more structured drape and help pleats hold their shape, resulting in a fuller, more traditional look, while lighter fabrics allow for easier movement and a more relaxed feel. Weight also impacts warmth and suitability for different environments, with heavier kilts often preferred for cooler conditions and lighter ones for everyday or warmer use. The choice of fabric weight plays a key role in how the kilt performs and how it looks when worn.
