The funniest thing is all this garbage with the numbers, the only numbers that have ever actually been affiliated with Nami is 3, because she was the third member of the crew, and Sanji is 5. Other than that, there has never been any other kind of number associated with them. The things people come up with sometimes X'D
Nope, people didn't come up with 7-3 today because Nami was wearing it finally. They came up with it years ago.
