If I can get it, I'd love to have the lvl 70 PVP gear that modeled after T5. Season , was it? Barring that, I have part of T5 and T2 in the process, all of T10 and most of 8 (which I loved). The "Pseudo Absolution Regalia" show on the site Callu linked is pretty awesome, too.
However, what I REALLY want? The tribal the better for my troll priest. :D I have a headpiece from back around level 20-ish that is all beads and feathers, plus the Beaded Sandals (which actually show up on a troll, last I checked). Although the latter is white and I seem to remember reading that they won't all Transmog of white gear? Anyway, I HAD a dress at the same time as the headpiece that looked like my girl was wearing a beaded, reed chest covering, tribal skirt and nothing else. I'm trying to find something similar on the provided sites, but I can't seem to find it. :/ In the mean time, I DO have
Robes of Dissention, which still looks pretty badass. ^_^
EDIT: MIGHT be
Raincaller Robes, because I was questing in Southern Barrens mid-LK.
