Dresses are a timeless wardrobe piece, serving as the fashionable backdrop to some of life's biggest and best moments. Even when a day doesn't call for something formal or office-friendly, a house dress can serve as a comfortable alternative to stretchy pants and casual tees. And since most dresses can easily transition between Southern seasons, you can truly never have enough—especially when you're getting them on sale.

Amazon Prime Day is here, and with it comes the chance to save big on many gorgeous summer dresses. From a tank swing dress made for running errands to a wrap dress dotted in a darling tulip print, the selection is seemingly endless, so you're sure to find your new favorite look. Other dresses worth considering include a "comfy" summer option that comes in multiple pattern variations, as well as a sleek silk dress.
