I am considering purchasing a Sherrifmuir with 5-button matching waistcoat. I like the look, and can also wear it with tartan 5-button waitscoats I own. I am unsure what shirt/collar works with a Sherrifmuir. Also, one cravat I would like to use with it is a ruche. What collar is a ruche worn with? It looks like it might not work with a wingtip collar usually worn with a PC. Any advice/info would be appreciated!
