Halloween // Looking for a Doris (from Shrek) costume but I'm having some trouble with it.

Hi, my friends and I are going to dress up as the Shrek cast and I'm going to be the Ugly Stepsister Doris. Here is a photo of her:

The thing is, I've been looking for a couple of days for women medieval costumes or women medieval dresses but I haven't found anything remotely close to this. There is a guy which dress up as her a couple years ago which I find perfect, here it is:

I found the man's instagram and wrote to him but he hasn't responded. I was hoping if anyone here could find something similar to either the original or this last version.

Thanks for your help.

Edit: also I found this reddit post (https://www.reddit.com/r/HelpMeFind/comments/xl8fqn/help_me_find_this_purple_dress_possibly_a/) where someone also looked for it but the links are dead and doesn't lead to anywhere.
