Funny thing, My GF has almost the same outfit. She was in the target audience for Pokemon when it came out in the US. I on the other hand remember wondering why my three brothers thought it was the coolest thing ever.
Boo! Pikachu isn't even top 10, and there was an official 2020 vote for most popular, and greninja won by far. Anne should know that, since she is popularity hunter.( Also mimikyu was in the top 10.)
