If you’ve never heard of Aritzia may I suggest you get acquainted. They have the best selection of simple shirt dresses. This one not only has pockets, but the fabric is so light and comfortable. I wore it to a wedding in Arizona and it was perfect for the hot weather.
Mine is burgundy (although it photographed red). They also have a mint one for spring that I have my eye on. This is one dress you will wear over and over.
