OnStopPlus is a great online store for summer dresses, and most online retailers will update their collections weeks before the summer hits. Your local retailers will also begin carrying summer selections before summer arrives; some such as Walmart and George will even sell them at discount prices to move the items before they become overstocked and they are reduced to clearance prices.
The best thing I could find when researching this is to go to overstock and look there for the latest dresses. The will have the color you want at the price you want.
