I don’t buy anything that needs special care. I Have two laundry baskets, a white one for white and a green one for everything else except for bed linens and kitchen items (Dish towels and cloth napkins). The bed linens get done once a week in their own separate loads and the kitchen stuff gets its own load so I can sterilize it. Clothes go in either the white or the colored load and are washed on normal setting (cold wash, cold rinse). Most stains come out in the wash, but Any clothing that is too stained or raggedy to be socially acceptable gets worn when cleaning, doing yard work or working in the studio. I like to keep things simple.
