What's this from?

I might be wrong if there are other CG Precures, but I'm pretty sure it's from Go! Princess Pretty Cure's movie.

You'll probably want to watch https://myanimelist.net/anime/28669/Go_Princess_Precure before watching the movie.
In case the PreCure franchise intimidates you, I'm pretty positive you don't need any knowledge of any of the others in the series to enjoy a different one. It is a series for kids after all, so it'd make sense that every new iteration would be easy to get into with little to no knowledge needed beforehand.

As a Pretty Cure fan in general, it's hard not to recognize the style and brooch.
