Yes, buy several sets of the same outfit; rotate them so she's in clean clothes. Try baby wipes if you can't get her into shower or bath. 'Sponge baths' at the bathroom sink if possible. Just as little kids resist baths, get creative to get her cleaned/freshened up.
Buy multiples of the same outfit and eliminate the battles.
Ironically, I worked one summer at Caltech in the physics department, and one of the professors in there never seemed to change his clothes. He wore the same shirt and pants every single day, but as he didn't smell bad, I finally realized he just couldn't be bothered to decide what to wear every day, so he had multiples of the same shirt.
He was extraordinarily brilliant and a Nobel Prize winner, so who was I to question the fashion choices of Richard Feynmann?
Grab those dirty clothes and get them washed as quickly as possible. Both my husband and I are only children and we had issues such as this (along with tons more) with our mothers. If she lives with you I would state that she needs to bathe maybe starting with once a week,every week. I know it won't be easy but you need to start somewhere.
This is typical Alzheimer's/dementia behavior. Hire an aide to bathe your mother once a week or watch some Teepa Snow videos on YouTube on bathing elders with dementia. Her tips are fantastic.
