A glamorous mansion on Sarasota Bay is the setting for one couple's colorful, sophisticated fête.

Erica and Guillaume met in 2004 in New York City, where they currently reside. "In high school, my family invited an exchange student from France, Martial, to stay with us, and we stayed in touch," says Erica. "In 2004, he visited me in New York with his girlfriend and his best friend, Guillaume—and the rest is history."

She wore a Matthew Christopher gown, and Guillaume sported Hugo Boss attire.
