This Ferengi costume is a bit hard to spot in the season 4 Deep Space Nine episode 'Bar Association', but it is there. Even though it may not one of the more sophisticated Ferengi costumes, I am lucky to have the complete costume in my collection.
The late Bernie Bielawski portrayed this Ferengi, and his name is on the inside tags. The shirt is custom made for this episode, while the jumpsuit and vest used for this episode came from a different Ferengi costume used earlier in the series...a common practice employed for a number for the Ferengi in this episode.
Sadly, the best image of him is in this behind the scenes photo.
