Well, we're both the same height and have the same problems finding clothes that fit us:
With his oversized suits, grandfatherly sweaters and shirts that swim around his sleeves McCain's sartorial blunders are often magnified by his impeccably styled wife Cindy, who does dress like she belongs in The White House. Look at any un-posed long shot of McCain and his entourage. Can you find him? No. Try looking for Cindy first, then for him in proximity.
In a world dominated by visual images, McCain has the fortunate opportunity to have what every shorter actor wants on camera… a female costar that can make him look taller. McCain can look at least 5'9" standing next to his lovely wife, if dressed in the right wardrobe. However, all too often it just looks like he's trying to ride her coattails into the White House.
Special credit to the gf, who's been telling me this for years.
