A few that I can think of off the top of my head.
Apparently my great grandmother. She was according to my mum a lady of taste but she insisted on safety pinning her old clothes together - seems she was a tight old biddy to boot. This supposedly caused the family some embarrassment as she could more than afford new clothes, just chose not to. This was told to me in my teens as I was going thru my goth/grunge/punk phase. Often my clothes then had more safety pins and rips than actual fabric.
She also used to steal cuttings and suckers from plants whenever my grandparents went to visit National Trust places - again her reasoning being to save money, she was a member and had paid her dues so bar nicking the furniture and fittings I think she felt that anything she could surreptitiously clip off with her shears was fair-game.

When I was going thru my afore-mentioned goth/grunge/punk phase I used to sleep 'rough' occasionally with a bloke who called himself "vomit". He would regularly tag his name with a permanent marker, often with the added "in my mouth". A local band - "Elf & the Goon Gut Babies" even wrote a song about him. Bathing, changing clothes or behaving like a normal human being were alien concepts to him.
One day I caught up with him and then we went to meet his family - I enjoyed a lovely breakfast hearing all about Richard and his very upper-class upbringing.
"Richard."

Me.
I mostly wear shorts & a t-shirt. I pretty much wear collared work-shirts at work.
I have dressed the same pretty much from child-hood.
I also only wear second-hand clothing (apart from my underwear and socks).
Hello Great-Grandma!

There were many people at my mums funeral that were surprised
that I turned up in a buttoned shirt & slacks.
They'd all expected me to to turn up in my usual shorts and a t-shirt.

I regularly turn up at work dressed in King-Gee work shorts and my business polo shirts.
Shocking tho it may seem.
EDIT: On my feets I favour a pair of Keen runners (my 2nd pair of the same type) or at work I wear Blunnie (steel-caps - www.blundstone.com.au/products/detail?id=29)

Janet, when you speak for all of us.
That's when I officially give up on humanity.
