Do any of you have experience with dressing your very elderly moms or female relatives?

I know a sweet one...she is my ex-mother-in-law...who is in need. Her eyesight is failing and so she can't tell whether or not something looks presentable. She spends a long time every day trying to figure out what to wear with clothes that don't work. We are looking to help her get rid of most everything and replace them with easy care fabrics that won't wrinkle and that have elastic waistband...she needs Depends at this point....so she also wants tops that can cover her bottom.

She is still beautiful. She always reminded me of Rita Hayworth. I'd love it if it were some fabric that looks nice, not fleece or pajamas, or Golden Girl lounge suits :). I just don't have much experience with wearing this type of clothing, so not sure where to go. She could have a stack of pants and tops, like a uniform supplemented by some really pretty scarves. She lives in elderly housing, and they don't actually let them walk around in their pajamas. She just needs some help keeping up appearances and at the same time making her life easier, like the rest of us I guess, but the requirements change.

I knew if there was any place where people were in the know about this, it would be YLF ! Thank you in advance and sorry this is sooo long!
