I love weekends away during the summer and find myself packing all the time. To keep things simple and save time, I choose a few colors and repeat them through so everything matches back.
For the beach, I love sunset hues: navy, coral, hot pink, shots of yellow, and taupe and white to pair with them. I never travel without a few python print items (my python jeans and The Shirt in nude python) which I consider neutrals. Of course, I include a stack of The Shirts in vanilla, navy, orange sherbet, and crisp white as they're perfect for day and night.
