J. Crew does have a white trouser that I will try. My only issue is that they don't come in a "short" length, while BR's do. The J. Crew inseam is 33", which means I would have to hem off at least 2 inches just so I could wear it with heels. I like the look of the J. Crew denim better, though. I just don't want to mess up the line of the jeans by hacking too much off the bottom.
I will look at them next time I am there. I tried their "hip slung" denim this even and I love it! It's the only bootcut that I feel is fairly flattering on me. The rise is really nice, too--just where I like it. If you are like me and are curvy and have short legs, you might give it a go.
