Confused on Large Train Bow Skirt

Coming to this reddit as it made the most sense to post it here. I don't get the entire hype behind the Large Train Bow Skirt. I won't deny that it's pretty, but why are people saying it's worth is close to 500k - 1 million?? Is it because it was released in 2018 or because of its history? The original price was 33k and I can understand if the price inflates, but I still don't get it. I've tried to find discussions on it but have only stumbled upon the wiki giving information about the skirt itself and or people saying what price it should be. I would like to get a response from the community as I would like to learn information on the worth and value not only price wise, but its sentimental value within the community. (Edit: It's been awhile since I've posted on here so apologies if my post sounds weird.)
