The costume is a white textured, long-sleeved, martial arts uniform with a zip up back with cuff and collar accents.
Worn by Brian Bonsall as Worf’s son Alexander in the Star Trek: TNG season five episode #210 “New Ground,” which aired the week of January 6, 1992, and the seven episode #273 “Firstborn,” which aired the week of April 25, 1994. Alexander first wore the costume while sparring with the Skull-faced alien in his father’s Holodeck calisthenics program. When we next saw the costume, a grown Alexander returned from 40 years in the future to change the upbringing that allowed him to become a pacifist diplomat duped into allowing his father’s eventual assassination. He wore the costume while accompanied by his future self into another Holodeck program. The costume consists of a white textured, long-sleeved, martial arts uniform top with a zip up back with cuff and collar accents and a matching pair of pants with leg bottom accents. A white tag in the uniform top collar reads “Brian Bonsall” and the costume tag reads “Brian Bonsall/Worf’s son.” It’s a Wrap eBay Auction February 17, 2008.
