I am currently working on trying to clear as many of my achievements as I can how ever on the Achievement tracking page all of the achievements for item layers have 0 tracked, but I have a fairly full wardrobe with many items in each area of the wardrobe.

I have the same issue so following this.
@Last_Chance
Idk if it still works but have you tried manually updating the achievements through the following page (https://subeta.net/wardrobe_layerachievements.php).
It's not working for me unfortunately. I get "Success! Your fingers layer achievement count was updated to" and then beneath that a bunch of misformatted images with errors including "This web property is not accessible via this address." and saying I need to complete a captcha but there's none that I can see.
so I tried that but unfortunately i got a similar issue to Last Chance i did nab a screen shot of it

@Last_Chance
ah it was worth a try, only thing now is to wait till staff add a change to the wardrobe so the achievement gets checked there or when they get around to fixing the achievement page which will be on their radar when this report is looked at
This has been reported below. I beleive once they have worked out the salon, that they were planning on working on achievements.
* Layer Achievement Update Page Not Working?
Please direct all reports there and they will update when they can. Locking as a duplicate.
