What makes a dress a summer dress? Well, the cut for one: these types of dresses usually expose much of the shoulders and the have low neck lines. They tend to stop just below the knee, showing leaving part of your legs uncovered. They also tend to be made of light material, so as to not be too warm, lace is often used so that some air can flow through the fabric, and they are often available in light colors.
Here’s an example in three different colors – I love these:
