Flower Wings. +20mdef +6def
I haven't seen anyone wearing them lately. It's great def for newbies and I'm pretty sure it's the best armor-slot anti-magic equip until you can get something like high-refined Frus carded armor or gtb or maya card.
Also, I think the refine rate adds *double* the def than normal refining does (which, if irowiki is right, means +1.32 def per refine instead of +0.66 per refine). So when refined high enough it'd be better overall def than other armor with better base def, even when the other armor is refined to the same point. I've only gotten my Flower Wings to +5, but eventually I might do the quest again
