This classic navy dress is understated perfection. Made from a heavy knit fabric it will flatter many body shapes. The longer length and open slit are very on trend. It is the most comfortable event dress you will ever wear but pair it with sneakers and a white button down and you have the perfect outfit for a summer lunch.
The model who typically wears an XS or a S is wearing a size small in this photo. You can size up if you want a casual fit or size down if you're looking for something more fitted. The fabric has a moderate amount of stretch.
