It’s the mid-summer wardrobe staple every woman needs in her closet. Light-colored, natural fabric tends to help reflect heat, and a flowy white number can help hide sweat marks and keep you cool on the go. Whether you’re heading to the office or brunch, here are some of our favorite white summer dresses for both work and play. Whether you’re heading out of town to celebrate midsummer or simply want to enjoy the longest day of the year at happy hour, a little white dress will help you officially get in the summertime mood. As far as we’re concerned, a white dress is the season’s unofficial uniform: Simply add a pair of easy sandals and a little bauble, and you’re dressed for virtually any occasion.
