Hello everyone, how yall doing? I hope you're having a great day!

Now, jumping into the question, might sound really dumb but I'm completely confused... About 2 days ago, I found a dress in my loft. At that time, I couldn't use it for some reason... It was just... There. When I went to "My Things" tab, the dress had no tag (as in, it didn't say the store where it was from or how I earned it). Today, I tried again, I can wear it and it says it's a Collector's Item. However... The dress isn't part of the trophies and I can't find it as a prize on any quest or event. Anyways, I am extremely confused because I don't remember getting it at all... I thought it was a little prize that OMD was still working on (example, sometimes you can get those gifts before the news appears of the front page because of some delay) but turns out not to be the matter.

Welp, does anyone recognize this and know where it is from? I'd really appreciate!
