I own and am wearing the and it appears in the wardrobe, but won't show up on my avatar. I'm not wearing too many layers and every other clothing item appeared, and they were all saved at the same time in the wardrobe.

I'm tried waiting and a hard refresh but it won't appear

Barely a minute after I added the flower headpiece I'm currently wearing.

There have been some cache issues with the wardrobe lately. I would try saving again and see if that works.

Since I see that it has appeared, I am going to lock this up!
