Missing clothing item

I got myself a snazzy hat from the steam market yesterday, but it still hasn't shown up when I change appearance. Any tips?

And yes, I did look through all the different tabs.

Staging branch?

Regular-schmegular steam release. No betas. 
Other purchased items appear, just not that 1 hat.

Well, probably this should be fixed in the staging branch in steam, it will be merged into the main branch only at the beginning of the new month. And tell which other hat doesn't work, maybe Garry will notice it. I think there in forum was a thread here somewhere related to clothes.

Updated to the October version, and still my Santa's hat only exists on my Steam account, and not in the character appearance editor 🎅 Someone else complained, 3 months ago, about a Valentine's piece being missing for him too.

Dan is gonna look into this today

any update. santa hats still not visible in anyones inventories. its happening to me and my friends as well. 

These should be visible after today's patch
