The 23rd century Gorn tunic only comes with a 25th century chest underneath it, whereas the 'Sleeveless Klingon' 23c. shirt has the proper 23c. Gorn chest underneath. The Tunic needs the proper 23c. Gorn chest to go with it. Also, this Tunic should be moved to the 'Bare Chest' listing as it is a mostly bare chest - lol.
Thanks!
