"Princess Grace's dress having darkened" I haven't seen all the posts Adele refers to as I am in digest, but received hers.
I think all natural light colored textiles yellow or darken unless treated again to whiten/lighten, but that weakens fibers. Different things, from processing, assembling, wearing, cleaning, and storing factor into that, but no doubt they turn away from their white of origination. Silk and wool are even worse for it, and a white silk blouse or wool coat, will knowingly come back more yellow and darker with each drycleaning, because of the chemical process and heat (even if fresh solution), in addition to time and air, oxidation, etc.. I think the non-acid tissue is as much about eating away at fold lines and all related deterioration, than even in the yellowing, because of the acid (as the name states), but Jeri can address that in more detail, as I have never stored things in an acid paper.
