Helmut Lang- the dry clean only label sucks, but they can be definitely worn a few times before heading to the cleaners. HLs just look classic...and a bit more dressy than standard Levis.
Unless they're black, you can safely ignore the dry-clean label and just wash them regularly. I saw that on a pair of my wife's HL jeans, after they had been washed a few times, and laughed. As for me, I find myself wearing less expensive jeans from Sisley and Zara, mostly. But truth be told I favour moleskins or other kinds of casual trousers over jeans these days. Peace, JG
