Especially the jeans that I like, I don't want them to fade out or even destroy the look I bought them for. I've got a Taverniti So jeans that smells really bad, so I will wash them before wearing them the next time. But the Diesels are good for wearing them new and unwashed.
I don't know about you guys, but I sweat...and sweat doesn't smell purty.
That depends on the "sort of sweater" (sorry for the bad English) that you are. Some people don't...
