That suit looks to be a hybrid of a morning suit, a regular 3-piece, and DJ. Maybe it is the monochrome look, but I think that a proper wedding suit should have at least a different color tie.
I am now set on black-tie, even though it won't be exactly proper given the time of day- 1 hour is not that big of a deal.
I've already got the marcella shirt with bib, TALL detachable collar, a proper low-cut 3 button waistcoat, and bespoke bowtie. I've probably spent more money on accessories than buying a cheap tux. But if I had bought the cheap tux, I would have also been stuck with cheap accessories.
Now I'll look like a million bucks under my cheap tux.
