The Beachside Bash
You definitely don't want to leave home without a warm sweater to avoid the seaside chill, and don't forget your sunnies for optimal bride-viewing! Just in case the ceremony's actually on the sand (usually they've got some sort of carpet going on), we recommend packing some flops in an oversized clutch.
