DETAILS: FUNctional cuff buttons

Here is a detail of the sleeves on this navy tweed jacket.  There are 5 buttons total, 4 in smoky grey Mother of Pearl, and the bottom-most button in white Mother of Pearl.  The white button also has a white stitched buttonhole and is slightly larger in size than the grey ones.  Just an example of a "fun" detail for sport jackets that don't need to be so serious nor follow convention.  The fabric is the "true blue navy new tweed".
