Just thought I'd expand on Jora's personality a bit more (and why she uses the types of armour she does) it's nothing massive like Cris, Mist or Storm (she's not that important a character for that) but it should clarify some things (and why she'll occasionally appear in less revealing armour.)

Basically she feels her tits are the gods' gifts to the world and feels like keeping them covered up would be a shame to everyone around her. However when she enters super serious mode (most of my characters have some form of mental problems, it adds character) she wears her sovngarde steel armour (or any other less revealing armour) because she suddenly feels whoever is on the receiving end of ire is not worthy to bask in the glory of her tits.

Basically most of my characters (with the exceptions of TESIV Shadow, Kara in FNV and Storm in Skyrim) could fill a mental hospital (hell Teneicha would need a padded cell.)
