How do I tell my 60 year old friend with mental disorder that she can’t wear booty shorts and bras outside.

I’m a live in caregiver for my friend who is 60 she has a intellectual disability that makes it hard for her to pay bills for her self cook and clean and do errands on her own. She is still very high functioning but I don’t think she really mentally understands what her body looks like at her age and how inappropriate it is for her to come outside in booth shorts and a bra. I think she has delusions and sometimes it comes off as being rude and cocky but I chalk it up to her disorder. She doesn’t even remember to take a shower unless I tell her too, but she wants to argue with me about her clothing choice. I was told I’m the first person to give her decent amount of allowance and lets her pick out her own clothes. I want to give her hefreedom and let her pick out her own clothes but everytime I do she goes and gets booty shorts and clothes out the junior section. I’m not a professional I took her in last year because non of her family members could at the time. If you ask her everyone who was a caregiver before me was too strict and controlling but it’s really her lack of self awareness and cocky attitude. For example she told me a story of how her sister would humiliate her about not taking baths or having good hygiene, but when I try to help her with her hygiene or appearance It’s often a struggle. It’s always someone else’s fault and never hers. I try to get her to understand that she has to be well taken care of and presentable because the state can check in anytime. I just wanted to know if there’s anyone out there who ever dealt with this from there special needs friend or family. Thank you sorry if it’s tmi

Sounds a bit like dealing with my wife's dementia -- no problem with booty shorts of like that, BUT she's likely to put things on inside out, back-to-front, her disposable underwear over her pants, etc. My son and I try to keep up with what she's wearing, but at times she gets terribly upset if we try to correct her.

This is how she wants to dress to the store, to check the mail, she came out like this in front of my 13 yr old son, she does have ptsd, bpd, schizophrenia paranoia, and intellectual disability. She has very good long term memory csn tell me stories from when she was 2 years old, but short term memory is off. I’m taking care of her full time but most of the time she is rude cocky towards me. I’m more of a roommate/ caregiver but all the stories she tells me is how people did her wrong and mistreated her but she can be a lot to have to deal with. I’m giving the daughter a year to step in she originally doesn’t want to.
