My headcanon is that this is Bethann Amell's armour and that Leandra took it when she left to have something of her mother's to give to her future daughter.
I've added an optional file that adds the armour to Hubert's store in act 1 for a rather hefty sum of 109 gold. Keep in mind that this file is probably incompatible with any mods that edits stores.
I've also added a warrior champion replacer in optional files. This makes the male version of the warrior champion armour invisible though since the model is female only.
