I know EXACTLY the cloth you mean - I was looking at it this very afternoon!
From Dormeuil's Royal 12 book, right? Pin-width red check and the black cloth has a sort of shadow-check.
It's utterly gorgeous. I was thinking a 2BSB with hacking and ticket pocket for it.
I decided against purely because, well, I couldn't see what I was going to wear with it because I find it very tricky to complement black suits. The only black suit I have is a very classic black pinstripe and even that I sometime struggle to match to.
If you can think of a few shirt/tie combos you'd like to wear with the red check/black background, I'd say go for it, because the cloth is lovely.
(I ended up choosing a charcoal grey from the same book with a red pinstripe and a shadow-stripe for a 3-piece 3BSB instead.)
