Highland dress is the traditional, regional dress of the Highlands and Isles of Scotland. It is often characterised by tartan. Specific designs of shirt, jacket, bodice and headwear may also be worn along with clan badges and other devices indicating family and heritage.

Tartan is a patterned cloth with crossing horizontal and vertical bands in multiple colours, forming simple or complex rectangular patterns. Tartans originated in woven wool, but are now made in other materials. Tartan is particularly associated with Scotland, and Scottish kilts almost always have tartan patterns.
Three tartans; the left and right are made with the "modern" dye palette; the middle is made with "muted" colours.
