Several years before I retired, we started going business casual most days, ie, khakis and megacorp logo polo shirts. As they began to show age, I brought them home (from Japan) and put thm in the closet for eventual ER and use while out working in the yard. I've got northward of 20 polo shirts and 10-15 khakis. As it warms up, I'll switch to khaki shorts and left over t-shirts with my old running shoes for working in the yard, and flp flops for lounging around the veranda and pool. In the summer, I'm also considering pulling on the running shorts first thing in the morning, going for a run, followed by a dip in the pool and a quick rinse with fresh water, and then just wearing those clothes all day while I putter around...I stay outside most of the day anyway.
I still have 6-7 suits, a couple dozen long sleeve business dress shirts, and north of 100 neckties. I will wear these to church on Sunday for the next 20 years.
BTW, my dad retired 10 years ago at age 67, and is still wearing his old work uniforms for puttering in the yard.
Our annual clothing budget is about $3600(for the two of us)...I'm only two months in, but it looks like we won't be using that much.
