I don't really care whether it's two different washes and therefore not a "suit," I believe that denim is best in (and should only be used as) one piece of your outfit only, lest you look like a cowboy/hayseed/farmer (not that there's anything wrong with that if you actually are one). This rule should count for chambray, dark wash, stonewash-- everything denim. Calvin Klein is jumping on the uglywagon in April's InStyle, too, with a pale-blue cropped-vest/ankle-zippper jean combo (and a done-way-better-by-Helena-Christensen-Wicked-Game-style-rolling-around-on-the-beach shoot, yawn), which makes me long for the day when 80s nostalgia is just that: nostalgia, not imitation. Even Cameron Diaz looks less gorgeous than usual to me because I'm all crazy distracted by the unattractiveness of the two denims together:

...Whereas the chick on the right (is that some sort of Kardashian? I don't really pay attention), although I don't necessarily approve of denim shirts, at least improves it with the contrast of black and a lot of skin.
Guess, on the other hand, is doing Spring denim right with a single piece-- a faded vest, fresh because dark denim has been at the top of the wash-chain for a while-- worn with a soft and girly full skirt with lace trim. Gorgeous.

(OK so the bag is a little bit on the gigantor side, as is her hair, but I'm looking at the outfit, not necessarily the styling. Guess is always a little bit over the top; I'll forgive them).
How do you feel about the "denim suiting" look? I just can't abide and I hope I don't have to see it on the streets come spring! Unfortunately, it appears that I will. Sigh.
