By having it for a long time, and not ruining it. I buy shoes every other year, boots every several, pants when one of the 4 pairs I have fails, and tshirts once a year during a charity event. Hoodies and coats last a long time and I also replace as needed...If you don't spend money on clothing how do you acquire it?
When something isn't presentable its workout or work clothes, when it isn't even preventing me from getting arrested when I go check the mail, it becomes cleaning rags!
