This is a posable action figure from the Nendoroid series.
From the Good Smile Company website:
From the popular anime series "PriPara" comes a Nendoroid Co-de of Dorothy West wearing the Fortune Party Cyalume Co-de!
The colorful outfit based on various different uniforms is the sparking cyalume code of the Fortune Party brand. It's the same outfit used by her twin brother Reona. Be sure to display and switch outfits with the other member of Dressing Pafe as well as the members of SoLaMi SMILE!
