Kilt flashes, while thought of as unimportant to the kilt outfit, are actually very essential! The elastic garters, that are placed under the turn-up of the kilt hose, helps to keep the kilt hose up all day (or night) long. Choosing a colour is quite easy. It is recommended to choose either the base colour of the tartan, or a stripe with in the tartan. Either will offset the kilt beautifully.
