I just bought a pocketless version at J. Crew at the Domain last night. They cost $68.00. This is the best pair I have found. It's not their bermuda shorts--these that I bought are more refined and dressy, and would be appropriate for work. Since they have no front pockets, there is no show-through (nude undies are a must, though), and they have a very simple, clean look. They come in black and geranium as well (bright reddish pink). I am keeping my eye on the geranium ones.
Also, try Express. They have some "City Shorts" (knee length dress shorts) that come in white. Not sure of your size, but they only go up to to size 12 in all their pants (just FYI). They are cotton twill and heavier, so I didn't notice any major show through of pockets. I'm going back today to try them on. The J. Crew were more of a "summer weight."
I'm in the market for a second, really fabulously fitting pair, so I'll post if I find any as well.
