This style comes in a good choice of colors from neutrals and pastels to brights.

For a seashore wedding I would wear one thing a bit more flowy like the flowery and ruffly clothes above.

Draw inspiration from mix-and-match bridesmaid attire by choosing a color that coordinates with, but would not precisely match, the maids palette.

Remember to think about the time of year, time of day, geographic location and climate circumstances of an outdoor wedding.
