How to get such a skin on Abigail (Ghost)? (Don't Starve)

I saw such a skin (0:37 on the video) for Abigail (Ghost) on one of the videos of the celik, but I didn’t find it in the play store, I can’t find any information about this skin anywhere at all.
If anyone knows how to get it, I will be very grateful for help)

PS I can’t insert a screen here, so I’ll insert a link to the video under the spoiler and timecode.
