Beach Wedding Guest Dresses: Light breezy dresses and strappy sandals make the perfect beach wedding outfit. At this non-traditional wedding, there are a few ground rules you should follow in order to look great, remain comfortable, yet formal enough, such as bright colors, bold patterns, and sensible material. You need something that can keep you cool, so the lighter the material the better. If it’’s a formal ceremony, wear a long, elegant gown.  Semi-formal calls for short or tea length dresses, which are great because they won’t drag in the sand or grass, plus they transition beautifully to a reception venue held at a restaurant or ocean front hotel. Wear shoes that you can easily slip on and off.  Flip flops or sandals are a great option as long as they’’re on the nicer/dressier side.
