I've noticed that many people have the same problem as me; no matter what I do, my Sim always gets the EA gloves, even if they're not wearing them. I tried installing the mod that everyone recommended: https://www.tumblr.com/buckleysims/...te-an-outerwear but nothing changed. I tried installing it in the package folder, it didn't work, I tried in override and that didn't work either, so I don't really know if there's another way to install it, but it didn't work for me. I can't find any other mods and I don't know what to do, I'm super desperate.

Please, I beg you, if anyone could help me it would be great

If you're using NRAAS mod. Have you tried to add the gloves to CAS blacklist?

I do use Nraas but I've never tried what you're saying. How do you do it?

Simply, open CAS and Ctrl+Right Click on the item which you want to add to blacklist. It will not appear in CAS or be added on townie thereafter. However, you need to change or remove the item if this is already existing in your save game.
For further details, you can google "nraas cas blacklist." I'm sorry that I don't know why I was blocked by the nraas website and can't provide the link at this moment.

Specifically, NRaas Dresser is what you need. (Plenty of other good stuff there, too, but remember to read the descriptions before going on a downloading spree.)

A touch of clarification -

MasterController's Blacklist is fully functional / standalone without Dresser - the two can complement eachother, but it's not required.
You can also use NRaas Retuner to check if the value from Buckley's mod is being applied.

I would suggest testing with all mods removed except NRaas and Buckley's mod - as it's not normal behaviour for this to happen, one has to troubleshoot what is causing abnormal behaviour.
