If owt get stained then it’ll get washed straight away.
Jeans usually about every 2 weeks sometimes leave it 3
T shirts when the pits smell, so about once a week.
Wash my jacket that I wear every day about once a year.
My cycle clothes when the smell gets to “that could gag a maggot” levels
However I have a shower every morning and wash my hair, so this helps with keeping my clothes fresh.
