The term KILT PATTERN is used to refer to the pattern of a traditional Scottish kilt. The two most common types of kilt patterns are PLAID and TARTAN. PLAID is a pattern consisting of criss-crossed horizontal and vertical bands in multiple colors, while TARTAN is a pattern consisting of criss-crossed horizontal and vertical bands in multiple colors, but with a set pattern of colors and widths. Both PLAID and TARTAN are commonly used for kilts, and both are considered traditional Scottish patterns.
