My friend said that you would eventually be able to buy the Nebula dresses that were in the Holiday Event classification in the Holiday Shop, since they were classified as Holiday Event items. I tried to explain to here that you won't be able to buy it again, unless in the trade broker. She wouldn't believe me and I got super annoyed and so I asked her to prove her claim. I think she started to believe me in the end when she said she didn't care and that I should prove it. So I am asking the community for the answer to this question so I can show this to my friend and prove her claim wrong.

While you shouldn't argue over something so silly, the Sunburst Nebula set is only available as a 'Forum Game' item. The other 3 sets will only be available from Holiday containers.

At this time, there is no plan to place them in a shop or outside of holidays.

I know, but I didn't want to get her hopes up, Then to crush them down when she figures it out, and have them to fall further.

It was more like bickering.
