Both mom and hubs tend to wear the same things everyday. I know hubs sleeps in his, and I am lucky to get them laundered weekly. Mom forgets to put her things in her laundry basket, so facility doesn’t know to wash them, then she is wearing the same stained clothes whenever I see her. I try to sneak them in her basket when she isn’t looking.

My husband will wear different clothes, but he never thinks they are “dirty” regardless of how many days he has worn them. I put his dirty clothes in The laundry at night, but lately he will wear the same t shirt at night and not want to change in the morning. I agree that you should give him a choice, but if is doing his own laundry maybe you can sneak into the laundry room, take his clothes out of the dryer and put something else in. May that pair of clothes is like a baby with a special blanket or Teddy Bear. Alzheimer’s people generally don’t like change so if it applies to clothes perhaps getting a few outfits that are very similar. Good luck

How about giving him the opportunity to select a top and bottom for M-T, W-TH, F-S, then Sunday. ...his choice, each day?
Making a selection decision on wardrobe or a menu is beyond his capability. YOU show him 2 alternatives...he chooses.
Worth a try. We saw this with my MIL and with a friend with dementia. It worked for them.

Yes people with AD do not like change. A real problem when change in clothing is the issue. My pre AD husband would be ashamed at himself if he was rational. Sigh!

Such a common problem . Folks lose reasoning ability. My husband used to be very clean. Now he thinks I'm crazy when I say people change underwear daily.
If it's going on too long, I tell him he stinks and that we can not go out anywhere if he smells bad. That other people don't like it. So far that works. My husband sleeps in clothes he wears next day/ days. He truly feels it is too much physical effort to change. I may bribe him with going for a ride or lunch.
It's a hard one!!
