I recently snapped a MoP button on one of my shirt cuffs. I don't have any spare buttons at home, and I am not particularly fond of how thin the factory buttons are, so I am considering replacing all the buttons on the shirt. Are there any recommendation on where to get MoP buttons online. My first thoughts would be Acorn or HWA Seng, but I was hoping to find an online haberdashery based in the US (or brick and mortar in IL).
I would appreciate any insight.
