Does denim that says Dry Clean Only really have to be dry cleaned?
I've got a Freedman denim shirt which I never really wear because I don't want to pay to wash it every time and it traps any environmental smells. The material is similar to http://i1.farfetch.com/10/06/54/71/10065471_348477_800.jpg (without the leather). It's smooth almost to the point of having sheen/luster
Also a pair of Marc Jacobs skinny jeans (2% elastane I think)
Do I need to follow their instructions or can I just cold wash and hang dry? My only concern is potential shrinking, they both fit well.
