ok so i put on an outfit that i have to hide part of my arms for i am using a legacy body and i saved the outfit. i make another one where i have to show the arms i hid but hide my shoulders so i do so and then save it. but each time i switch to the first outfit my shoulders are missing and the arms are correct, i have to fix the shoulders each time even if i fix them then save. same for the other outfit that shows my arms, the outfit was saved with my arms correct but when i change they are gone. does anyone know a legacy body enough to fix this issue? or do i have to keep hiding and showing these pieces each time i change looks?
