• Be cohesive yet creative
• Don't be afraid of bold colors
• White is great, but mostly for the beach photos
• Jeans work with any outfit
• Patterns are welcome as long as not mixed or overwhelming.
• Avoid graphic tees
• It is best for all to wear two main colors (do not be afraid to mix shades), but a touch of a third contrasting color can work really well and add a spark.
