Maybe try cargo pants?

I’ve kept my wallet in my left rear pocket since high school. Then at night it goes on top of my armoire until I get dressed the next day. When I take it out in public I immediately put in back in my left rear pocket. It’s a good habit to develop.

I keep mine in certain pockets in my jackets. There are wrist wallets too, some look a bit weird but you could probably find a decent one online.

Never allow your wallet to leave your hand unless its going into your pocket or a assign spot in your home. I had this issue bad but nowadays my muscle memory is trained to never set my wallet down anywhere. Its either in my pocket or kitchen table. I sometimes forget what I'm doing and will just hold it for 45 minutes or so while watching TV not realizing its in my hand.
