For my 2014 interview I wore a charcoal colored Mr. Lim PCS special I'd purchased in 2004 (I didn't have the ca-hones to go with the olive green suit) along with burgundy wingtips I'd purchased in college back in '93. I might have been wearing underwear from a decade ago as well. They don't care what you're wearing, if United had called me just a little sooner for an interview and I had a backup I might have given olive green a go just for the notoriety I'd have earned.
