Best Man
Brother of the groom, need we say more?
Maid of Honor
Jessica and Melissa met freshman year of high school and have been best friends ever since. They've taken on cities like Chicago (Jessica attended University of Chicago) and New York (where they were roommates just before Melissa & Jake moved in together) together.
Bridesmaid
Alex and Melissa met when they lived in the same hall during their first year at Northwestern University. Although they've never lived in the same place for more than 4 months since then, they've stayed best friends throughout all of these years.
