It don't have a J. Higgins kilt jacket so I can't comment on quality.

Keep in mind that J. Higgins makes their jackets in house. So, they should be able to make you a PC type vest out of the same material they use for their Argyll style jackets. According to the website, the black Argyll waistcoat is made of the same material as their black jackets. So, the jacket and both vests should match.
