So I searched this first, but the threads are dated and I still haven't found a good source of the buttons I want to use. I bought a navy sport coat (yes a sport coat, not orphaned suit), and I want to put higher contrasting buttons on. I was thinking either white or brown horn. Thoughts? It's a wool Zegna sport coat. I really like mother of pearl and the color white, but it's my only plain navy sport coat so I was thinking of going brown horn. Any source for nice medium brown horn buttons?
