The National Office of Buddhism (NoB) will submit a letter to American clothing brand Supreme to protest against its use of an image of a monk.
Supreme's new Blessings Ripstop Shirts feature the well-known image of the late monk Luang Phor Koon Parisutho.
The image, which appears on the back of the shirts, is of the monk smoking. The shirts also feature several "yant" prints.
The NoB will send a letter to Supreme to explain how it is inappropriate to use the monk's image on its clothes.
An official at Luang Phor Koon's temple Wat Ban Rai said yesterday they were never contacted by the clothing brand and said the company should have asked for permission.
However, the preview of the Blessings Ripstop Shirts has reportedly caused excitement among Thai customers.
