Who market Gaelic attire for women

[Pleater]

Neither image is a correct interpretation of historically correct costume - though few are likely to be bothered by that.
If you did want garments made in something like an accurate style then it would cost a lot to buy due to the time taken to make it, so it would be far thriftier to obtain fabric and pattern to make at home.

It would also mean that you could match the social standing of your costumes, assuming that you are going to dress as a pair from the same location - Gaelic is a modern term and it would probably mystify a scholar from the time referred to.
