Finally stumbled upon this wonderful resource on men's formalwear guide (http://cgi.www5b.biglobe.ne.jp/~akanbe/yu-betsu/joyful/joyful.cgi?page=20) formalwear accessories and I can honestly say it totally transformed how I approach my wedding tuxedo styling!
Before reading this I had no idea how to properly coordinate formal suspenders for men with the rest of my formalwear setup, but now I see exactly what to do. The section on tuxedo suspenders and bow tie was especially helpful because I always had trouble figuring out whether formal suspenders for men should match the bow tie.
This tuxedo styling guide lays everything out clearly, and I have a black tie event coming up so the guidance on men's formalwear accessories came at just the right moment — seriously bookmarking this!
