I made an inventory of sorts for those who like to collect all of the outfits from the workshop. I finally collected everything available in the workshop earlier this year and figured I would catalog the list that PUBG has available in case others want to see what they are missing or how close they are to having everything. I've been keeping up with it each update since July or so when I first finished it, and this one is updated with today's update's additions to the workshop.
I'm not sure exactly how Google Docs works, but since this is public, I am assuming you could save it as your own doc and edit it however you see fit. For instance, add a checkmark in the B column for items you own or delete any items you own until only items you don't have are shown. Of note, the order the inventory is arranged is the order they were added into the workshop, with the last parts of each section being the most recent. This logic only changes slightly in the emotes category as I wanted to keep all the numbered Victory Dances in numerical order as much as possible.
One last note, these items are items you can acquire from repurposing 3 items of the same tier. There are some items like makeup designs, hairstyles, gun skins, etc. that are only able to be acquired if you craft the whole set they appear in.
