Clothing is not made in Poser (at the most in Poser "plugins"!). Much  Poser clothing in the past has been created in older versions of Carrara even!

So, it is possible to make horns and clothing in the Carrara Vertex Room--if you are prepared to put in the work.

All that Poser/Daz stuff is just "short cuts" supply--and mostly of real work done in Carrara type apps in the first place.
