How many people have worn the straw hat, if only for a second?

Question

How many people have worn Luffy's straw hat? Canon, confirmed, and on the head (I'm counting Robin even if she wore it atop of her other cowboy hat).

Answer 1

Here you can read who had worn the straw hat and what it has gone through during the series. I will summarize the list here and add proof from the manga. For the complete panel the thumbnails are cut from, click the thumbnails. Until chapter 801, it seems 7 people were seen wearing the hat.

• Chapter 2 − Monkey D. Luffy

  Luffy is the current holder of the straw hat.

• Chapter 1 − Shanks

  He gave it to Luffy as a young boy after he said the same words that Gold Roger, his former captain, had once said.

• Chapter 603 − Gol D. Roger

  Much later in the series, it was revealed that Gold Roger, the man who would become the pirate king, had owned that hat.

• Chapter 81 − Nami

  She is the member of Luffy's crew that he more often gives it over to for save keeping.

• Chapter 114 − Robin
  Not mentioned on the list, but as explained by OP, Robin had taken Luffy's hat from him during their first encounter.

• Chapter 314 − Usopp

  Usopp briefly wore the straw hat during the Davy Back Fight against the Foxy Pirates.

• Chapter 515 − Sweet Pea

  Luffy was in a panic when he couldn't find his hat, but it saw one of the women in the crown watching him wearing hit.
