This is Roger Federer's 2012 US Open Custom Personal signed night session outfit. This includes his custom shirt and shorts. Includes a Roger Federer signed certificate of authenticity. Likely worn by Federer during the tournament. 

The shirt and shirts made by Nike for Federer do not have any size label, but rather "custom athlete" tagging.

Federer entered the 2012 U.S. Open as the No. 1 seed, having reclaimed the top ranking after his 7th Wimbledon triumph earlier that summer. This outfit represents not only his enduring brilliance, but also his unique style and presence on the court during the latter stages of his Grand Slam dominance.
