Back in 1975 I was pregnant with my second child. I made all my maternity clothes . One day my mil looked at me and said OMG your skin is yellow!! you need to get to the doctor NOW! . Well good thing I waited a bit and finally figured out that the bright green maternity top I was wearing was rubbing off on my skin turning it yellow. Can you imagine what my doctor would have said? Now at least I know what it was called. LOL
