Strange, because I have a max level KDF toon that does not seem to have access to it.
It's a bug, Alex. The cloth bits seem to appear for some characters and not for others. I have reported it on several of my KDF alts. Hopefully they will fix it someday. I wouldn't count on it happening soon though.
The Orion Male Harnesses have been stuck in the Armor category since Season 2 (when they obviously belong in the Bare Chest category) and there are numerous pieces that have gone missing for Females but still exist for Males or vice versa (Padded Boots, Leather Boots for Klingons, etc.) and there has been no word on fixes coming down the pipes for those.
