Giles & Brother cuff make it a must-have. I usually favor daintier pieces, but this has enough heft to stand out without being a "statement piece." Fall's chunky knits and long sleeves tend to call for chunkier pieces. It doesn't hurt that the interlocking rings bring to mind Celine's knot bracelet either.
