I will be attending a few black tie dinners over a short period soon. I have only done black tie a couple of times and have done SB, Cummerbund, Bowtie. Nothing controversial. However, I'd maybe like to substitute the bowtie with a black silk knitted tie and am unsure as to whether I can/should wear a cummerbund with this. I am not a fan of wearing a vest. Your thoughts appreciated please?
