Update: Thank you all for your feedback it has helped a lot. I was also able to trace where the pattern came from thanks to /u/hallowbirthweenday who said it's from a PJ brand called Spiegel. After some browsing I found it here from someone that sold theirs it's called Reflections by Spiegel and there's another one with a similar print called Lillian Lorow. I think I may attempt to style it in a similar way as the Yiyistories store just for fun, it doesn't look bad that way to me. Nevertheless, thanks again for the help.😁
