I love how creative we all have to become as carers, it is so difficult to persuade anyone with dementia about anything. My dad (although he didn't have dementia) would wear the same clothes and underwear for weeks on end and as my mum had dementia she just didn't notice. When I became the carer for both of them I was constantly finding ways to 'steal' their dirty washing to take home to launder for them. After my mum passed away I used to sneak into my dad's room knowing he slept naked and just whisk away his whole set of clothing and replace with clean before he even woke up. Thankfully he was very deaf and never heard me arrive.
