Just a quick update. The tailor agreed to switch out the lapels facings and the pant seams to black satin (with an "I told you so").
Because of the time it would take to get the vest made, and because I only have two weeks before some holiday events when I'll need my DJ, I've decided to go with a black cummerbund and bowtie.
However, I am
getting a waistcoat made -- I had originally wanted a DB waistcoat, but I was told that something along the lines of what Bill posted would work better. So, I've also asked for this, in a different fabric than the DJ or the facings. But given the holiday season, I was told it would take a while before it would be ready.
Thank you all, for your help. Much appreciated.
