This ladies’ shirt was made by GANT. It is a good approximation of the ‘ancient’ colourway, with the red sections tending towards orange. Mairi said:
I came across this shirt on Ebay, during a random search for tartan things. Like the Ralph Lauren and M&S shirts that use a version of the ‘red’ Macpherson tartan, this shirt is not labelled as a Macpherson.
