Since several are looking for washable cool summer dresses that aren't so short, you might check Eddie Bauer. They featured several in both woven and knit fabrics in the newest catalogue (Summer Book 2009). Scroll down past the maxidresses. Most are offered in more than one color or print and in reg, petite and tall sizes. I've liked their dresses in the past and they washed beautifully, but I haven't tried any of these yet. Our local store doesn't carry dresses.
