A girl in a purple dress standing in a dark alley with pumpkins

strikingly realistic yet anime-style depiction of a girl with long, vibrant purple hair. She should be donned in a unique Halloween-themed skirt featuring playful, spooky patterns like bats, ghosts, and pumpkins. The girl's attire should be completed with a black crop top and matching knee-high boots. Her eyes should possess a captivating shade of violet, reflecting her enchanting appearance. Render her in a dynamic pose that exudes confidence and charisma, and set the scene against a moonlit backdrop with a hint of eerie ambiance, enhancing the Halloween atmosphere
