Doctor McCoy's ( DeForest Kelley ) off-duty costume from Nicholas Meyer's sci-fi sequel Star Trek II: The Wrath of Khan. McCoy wore his outfit when he visited Captain Kirk's ( William Shatner ) quarters for a drink to celebrate his birthday. McCoy also dressed in a similar shirt and trousers in Star Trek III: The Search for Spock and Star Trek IV: The Voyage Home.

The outfit consists of a jacket and a matching set of khaki shirt and khaki trousers. The jacket is made of blue suede with a large pocket on each side, and features a large metal zip and a beige lining. The shirt zips up at the front, with blue suede detailing down the middle and on each arm, and two pockets on each side, secured with metal poppers. The trousers are made of the same material as the shirt and have a hidden metal fly.

A label in the collar from "Western Costume Co. Hollywood" has "Kelly De Forest sic" printed alongside other information, including sleeve length and neck measurements. The trousers also feature a costumier label reading "Kelly De Forest sic" and his waist ( "31 1/2" ) and inseam ( "32" ) measurements.

The shirt and trousers both retain their labels from their inclusion in the 2006 Christie's auction "40 Years of Star Trek: The Collection". The costume has some wear from age and production use, including some minor staining on the shirt. The trousers have some staining at the bottom of the right leg.

Value: $10,000.
