Originally sold on eBay during week 47 of the IAW auctions, I recently purchased this from a Trek forum member.
This gorgeous Vulcan costume was created for an extra in Star Trek III: The Search For Spock. It may have been re-used later in Star Trek VI: The Undiscovered Country.
It comes with costume tags naming actor Gabby De Lys as it’s wearer and both the hat and gown are labeled “3-13.”
