Hi everyone - I desperately needed a new winter coat, and bought this one in the Marine color to use as a stopgap while I continue my search for the one.

It's a classic, simple, functional all purpose coat, but it has these shiny plastic branded buttons that I would like to replace. This seems like a simple thing, but I've never had to shop for buttons.

Does anyone have any ideas of what kind of buttons would work for a coat like this? Any particular button trends out there? Or are black/tortoise/metal classics the way to go with a classic coat? And, if a classic, like the the subject says, is there such a thing as quality/high end/expensive looking buttons? Where does Burberry source their buttons?

Thanks for humouring a silly request.
