When visiting another community on craft fair day, a lady was selling adult clothing protectors that looked somewhat like a vest. They were classy enough for me to look twice, thinking it was something I might wear before realizing the purpose. It seemed like a simple enough item and since then I have wished many times that I had purchased one so I could replicate it for my mother who now needs something like that. She does use some adult bibs, but with mobility issues in reaching over one's head or behind one's neck, a pattern must be carefully selected. The link you posted, Janey, with the front shoulder fastener looks like it might be mobility-friendly.
