Socks should typically be washed after every use. They come into direct contact with your feet and can accumulate sweat, odour, and bacteria.
Bras can be worn multiple times between washes. You can wear a bra 3-4 times before washing it, as long as it's not visibly soiled or odorous.
You can wear a shirt 2-3 times before washing it. However, always check care labels for specific washing instructions.
Pajamas can typically be worn for a few nights before needing to be washed. Washing them every 3-5 wears is a reasonable guideline.
It's a good idea to wash your bed sheets every 2 weeks. If you sweat heavily at night or have allergies, more frequent washing may be necessary.
The frequency of washing towels can depend on personal preference and usage. It's recommended to wash towels after every 3-4 uses.
Denim jeans do not need to be washed as frequently. Jeans can typically be worn multiple times and it's recommended to wash them after 10-12 wear.
