[REQUEST] clothes for 56 year old veteran

I am seeking some very simple assistance for a veteran and friend.

He is a 56 year old veteran who is currently going through litigation for a disabling nerve injury.  He suffers intense migraines and is one of the most caring and nurturing people I have ever met.  He assists and cares for other disabled veterans and any bird, cat, you name it - he helps everything with a heartbeat - except himself.

This man direly needs clothes.  He is living in a demo trailer without running water and lives in deplorable conditions.  He has a stable job but seems oblivious to his appearance. He isn't an average veteran who has given up - he is very motivated although blind to himself in some ways

I know he should go to the VA but he is a proud gentleman who will not seek the help for himself.

Shirt size XL

Pants 36ish

he is 6 ft tall and we live in desert conditions (Las Vegas)

I would appreciate any help possible for him. I would do more but I also live on a limited income.

Thanks for your time reddit!
