Modifying Save Game File(s) in S4Studio question

I been waiting to dress up my entire sims population out of the game by using Sims4Studio using just bodyparts values and instance numbers, I clicked on Save Game Data, and under SaveGameDataResource, I looked for references that just covers each individual sim, I had to scroll nearly all the way down to a section named Sims and it seems each sim in the world is called SimData, I click one of those and their name is revealed along with everything else.

Then I finally see an Outfits tag, being the most obvious choice, I clicked on Edit Items, then a see a row of OutfitData(s) presuming each OutfitData is a category, but then clicking on it only really shows me outfit_id with a hex number I don't recognize.

So now presuming it's must be completely elsewhere, but I have nothing obvious elsewhere to look.

My Save game file is 74MB, I am getting a lot of freezes and Out of memory just by browsing so it makes it even harder to find what i'm looking for.
