Blue Calvin Klein shirt purchased at the X files 20th century auction held on Ebay. Comes with 20th century fox COA item #XFL0004 Mulder shirt. No episode name given tho a bloody shirt with bullet hole matching this one was also auctioned which came from episode "The Goldberg Variation" (1999) So this was probably the shirt worn before being exchanged for the bloody bullet hole one.The Goldberg Variation" (1999) screen capture
