I know that a black barathea argyle with chrome buttons is suitable for daywear formal as a highland version of a morning coat. As I understand it it can also be worn with a black self tied bowtie for some black tie events. The problem is that I have always been taught that a black suit should only be worn by undertakers and that it was less aesthetically interesting than other options. I know highland wear and Saxon wear are different, but I can't help feeling this way. I am willing to buy a black argyle if I must, but could a dark navy barathea jacket with metal buttons still be used in the same way? Would it still be suitable for black tie? Even my saxon tuxedo is Midnight Blue instead of black.
