Erin and Brian in Chicago, IL

A high school transforms into a lavish reception with an autumnal theme

Imagine hosting a wedding reception at your high school. Seems odd—unless, like Erin, you went to Saint Ignatius College Prep, where the elegant dining hall has sweeping views of the glittering Chicago skyline. One part nostalgic homecoming, another part autumn elegance, this soirée's glamorous vibe belies its down-to-earth hosts.

Erin wore a Vera Wang gown purchased secondhand at Wedding Belles Ltd. in Barrington. "The dress came in the day I had my appointment, and it didn’t need a single alteration," says the bride. "It fit like a glove."
