Starlight Celebration event equipment storage

[mosaicex]

It appears that I can't store the event equipments (Tunic and such) in the armoire unlike items from previous event.

Is this normal?

Yes. New event items aren't added to the armoire until some time after the event is over. This is most likely to encourage people to actually use it, instead of just stuffing it in the armoire as soon as they get it.
