Here's the chest-gear one in the "Uniform" category, which is the only one that allows the caitian tail, but it clips terribly no matter how much I mess with the body sliders. It's also only available in Terran glossy. Pretty sure I'm not supposed to be able to see my caitian's arm fur through his sleeves. You can also see bits of the undershirt poking out around the shoulders. Not a single Uniform shirt you can wear under it doesn't clip. Every single one clips very badly, but some are even worse. I've messed around with every slider I can, but nothing fixes it.
And this is the "Medical Coat" version instead of the "Uniform", which doesn't clip at all that I've noticed, but doesn't allow tails at all. It seems the "Medical Coat" category version's shirts slim down the arms a lot so they fit under the sleeves properly. Do Caitians just have weirdly bulky wrists no matter what?
Would be nice if the "Medical Coat" category one at least allowed tails, along with the other categories that don't, because as far as I'm aware only the "Uniform" and "Off Duty" categories let your caitians have tails. Also would be nice to be able to have the Federation / non-Terran one as an option in the Uniform category as well, at least when they fix that nasty clipping.
Edit: For comparison, this is the front of the Medical Coat category, to show how badly the Uniform version clips around the wrists and shoulders in the front:
