Does proper cleavage count as one thing or two?
There are several costumes that have low necklines revealing a uniboob. Instead of two distinct prominences, the unfortunate wearer gets a single bulge with a slight groove down the middle. The "Holiday in Balmora" gets it right, as do the Bosmer armors, and the Sand-Kissed Salwar outfit. But the Corseted Riding Outfit, and the Cyrod Patrician's Formal Gown have the uniboob issue, as if they were built on a different base mesh with no separation.
