Of course, the real answer is anything you want to! But to help better answer that question I have provided some examples of what I have found to be popular and well-suited outfits for the beach.
Popular Colors: Blue, White, and Tan
These are some of my favorite color combinations from some clients I have shot. They did a great mixture of using blues, whites, and tans in their color palette and they worked perfectly with Jacksonville Beach in the background.
Want to be bold? Use Red!
A recent client of mine decided to wear red for their maternity shoot and I loved how the color looked against the tan and blue of the beach and can definitely recommend trying this color out in your next beach shoot!!
