My mother gave up wearing a bra when she was in her eighties, and wore white cotton camisoles that were more substantial like tees. Hers were from Cuddl Duds I think. I would certainly ask your mom whether she wants to wear a bra again. There are a number of catalogs that feature clothing and assistive devices for the elderly that can be really helpful.

Your mom is not alone. Mine gave up wearing bras in her eighties and just wore thicker and looser shirts until her death at 87. She just wanted to be comfortable. I bought her pretty shirts to wear since it was hard for her to shop and she enjoyed wearing them.

Wow, I want to save these references ! Great ideas. Had to shop for my mom also and get things sized up for easy on- off, she insisted on 100% cotton. Did my best to try to get attractive colors, coordinate things since the fits were not great, when you make a lot of other priorities for mobility and comfort do she could dress independent, at least.
But was kind of “ this is your future “, too.
I do wonder what kind of compromises I will have to make and what kind of fun with fashion will survive. I think of my 2 DD’s maybe having to figure things out.

The bra lapse I get, not just as “ giving up”, but because by the time clothing is looser, thicker, and adding a loose jacket for older folks who may run colder—- then the adage of “ get a good bra fitting “ is kind of moot.

Thanks for reviving this thread, Tilly, and all the new suggestions. As an update, my sister bought my mother a front-closing bra marketed for seniors but the hooks are still too small for her to grasp easily. So it’s back to the drawing board.
