The kilt in other Celtic nations

Although not a traditional component of national dress outside Scotland, the kilt has become recently popular in the other Celtic nations as a sign of Celtic identity.[8] Kilts and tartans can therefore also be seen in Wales, Cornwall, the Isle of Man, Brittany, Galicia in Spain, the Minho region in the North of Portugal, as well as parts of England, particularly the North East. Nowadays with Welsh nationalism on the rise and a resurgence of Welsh national pride, the kilt (Welsh: Cilt)[citation needed]. Although they are generally seen these days in formal settings like weddings, there has been an increase in the number of people wearing their kilt to a rugby or football match, paired with a jersey rather than a formal jacket[citation needed].

The St David's Tartan or brithwe Dewi Sant is one of the most popular tartans in Wales, but individual family tartans are being produced, despite there being no evidence that the Welsh (or any other Celtic nation for that matter) traditionally used tartan to identify families. Williams, Jones, Thomas, Evans, and Davies are among the most popular tartans and common names in Wales. The Welsh National tartan was designed by D.M. Richards in 1967 to demonstrate Wales' connection with the greater Celtic world. Its colours (green, red, and white) are the colours of the Welsh national flag.

There are currently 12 Breton tartans officially recorded in the Scottish tartan registries. The Breton tartans are: Brittany National (Breton National), Brittany Walking, Lead it Of, and further 9 county tartans (Kerne, Leon, Tregor, Gwened, Dol, St Malo, Rennes, Nantes, St Brieuc)[9].

There are 2 Galician tartans recorded in the Scottish registries: Galicia and National Gallaecia. There is historical evidence of the use of tartan and kilt in Galicia up to the 18th century[10].
