Rosario Dawson Look for Less < $75

Everytime I see a sweet white dress in a store (like this one... ) I always want to snatch it up because it looks so sweet and summery.  But I never pick one up because they always seem so impractical.  How should I style a summery white dress in a way that makes it wearable every day?  I think this bright scarf and simple black flats that Rosario Dawson is wearing here is perfect!
