What To Wear?

My goddaughter is getting married June 21st on the beach at the Marco Island Beach Resort. This will be my first beach wedding and I have no idea what to wear. The bride's mom said the guests will be dressed in everything from shorts to evening gowns! She suggested a sundress, not too casual and not too dressy...so I've been searching some of my favorite sites for the perfect dress. I want to look good, but be comfortable at the same time. I've decided on a short dress and found several that interest me at Belle Avenue. Also, there's a lot to choose from at Roaman's and Sydney's Closet. I especially like Sunset Beach from Sydney's Closet. It's the perfectly named dress for the beach wedding I'll be attending at sunset! Love and best wishes to Megan and Aaron!
