Please don't force your groomsmen to relive regrettable style moments from a cappella history. Controlling the color palette is cool. 12 men in red blazers is ridiculous.
And as The Upgrader points out, the only people who should be wearing white gloves with black tie are the help. Don't dress your groomsmen (or yikes! the groom) like members of the catering staff. (Images courtesy of men.style.com)
