Stat bonus wise our AF+1 isn't super awesome.
If you do stuff where resists are a concern then body first. That's what I did.
If you do stuff where you can nuke for max damage often then head first. Unless you did max damage Moogle hat (INT+4 MAB+2).
If you do stuff where you're main healer/buffer a lot then hands first. These are a nice Stoneskin piece and the spell interrupt and -Enmity don't hurt.
As to Argute Gown it is an idle piece when you're charging Sublimation, know you're gonna get hit with Magic Damage, or can use it to up your Phalanx/Enspell/Barspell. Otherwise it isn't useful compared to other gear available.
