Upcoming formal!!

Hi so i have my year 11 formal in september (trying to prepare early lol and not miss out on this beautiful dress) and im obsessed with this dress but cannot justify spending $320 aud for it. could anyone find any reliable dupes? ive found almost exact ones from websites like hayridge, novora the label and ruby lore, but the reviews for those websites aren’t great. i’m willing to spend $200? maybe $250, help would be much appreciated!! (btw i live in australia) also sorry if this isn’t the correct community to post too, reddit recommended it and ive never made a reddit post before but i really need help.
