There's 4 hats which clip pretty badly, may have always been like it but would be good to have them fixed. These are Cone Hat, Shoe Hat, Saucepan Hat and Skull Hat. Updates for each attached.
Could you double check they're not correct when you're actually wearing them (as opposed to item preview).
Could you re-validate that the saucepan values are correct. I had incorrectly applied the scale on that + shoe, but shoe seems correct whereas saucepan still isnt.
