I like them too, but in a more limited range of fits/cuts than indigo jeans. They look a little bizarre and are more difficult to pull off when they're very loose or very tight, as well as when they have a pronounced bootcut or taper. 501's look good in white, but even better would be something with a little lower rise. It's too bad APC doesn't have a white New Standard; that would be a kick-ass pair of jeans. I also like some of the treated white denim from Helmut Lang and Diesel (at least the more subtle variety, rather than the kind with huge amounts of fake dirt splotched everywhere).
