I have been getting this issue, I made a thread about it, which @Avaluate has mentioned 
This has been re-occurring for 3 months now. I’m very down on sales. Im hoping now we can get some more attention to this. Which proportions type exactly are you using? If you’re using Classic, this is the expected outcome, and your accessory is simply out of its bounding boxes. However, if you’re using ProportionsNormal or ProportionsSlender refer to Incorrect Bounding Box
