For Engling’s wardrobe makeover, stylists swapped out his P. Diddy-era shiny jacket for some more refined duds. The magazine points out, “Co-workers will remember a loud jacket, for sure. A classic tweed, impeccably tailored, means they’ll remember you.” But fashion apparently doesn’t come cheap — Engling’s new tailored J. Crew suit set the magazine back $590, along with a $90 Polo Ralph Lauren shirt and a $140 Alexander Olch tie.

Another congressional aide gets a lesson in suit style in the issue. GQ advises John Deoudes, a House legislative staffer, to “vote ‘hell no’ on boxy suits.” The magazine writes of the 25-year-old’s “before” outfit, “John’s suit was at least a size too big! A real power suit hugs the shoulders and tapers at the waist.” Deodes, who gives a fierce model-like stare in his “after” photo, seems pretty pleased with the results, saying, “A slimmer fit makes me look 20 pounds lighter. I had no idea!”

But weight isn’t the only thing Deoudes loses with his new look — like Engling’s makeover, dandifying takes a lot of dough. The new wardrobe for Deoudes would cost him a lost of cash, at nearly $850.

Other guys getting some help from the fashion pros include a staff assistant for Rep. Jesse Jackson, Jr. (D-Ill.), a Capitol Hill construction project manager, an IT director for the Senate Committee on Banking and a speechwriter.

UPDATE (3:11 p.m.): Another "50 Most Beautiful People" alum made the GQ cut, just not in the print edition of the mag. Julian Malasi, who was a policy issues manager for the American Chemistry Council when ITK interviewed him earlier this year, is a part of GQ's online feature.
