I was watching a video on YouTube when what should I see but this very Marie-like hat. I couldn't help but save a screen capture to share with you. She wore one very much like this in her interview with Emme Tommingbang on "Emme's Island Moments / Memories of Hawaii Five-0."
We also remember her broad-brimmed yellow hat, which made an appearance in the Five-0 episode "Honor is an Unmarked Grave" (Season 8). We see Marie wearing it in this picture:
Interestingly, Marie was seen wearing this hat at numerous functions long after "Hawaii Five-0" ended production. She was also seen in similar hats in various colors, including white, olive green, black, and red.
