This is the 'Suit' costume worn by (and taken off by) actor Jason Mews as he portrayed the character of Lester in the movie Zack and Miri Make a Porno.
This costume appears in the scene where Lester begins filming his segment in the coffee shop 'porno' as a customer. He quickly takes off the suit and is left in the blue tie and black underwear.
When purchased I did not know that the costume included the underwear!
Screen-caps from the movie are included for reference.
