I'm assuming you're a DRK. Unless you go SMN or BLM, it'll be hard replicating the top.

Top: Songbird's Dress if you are DRK
Ribbon: Thavnairian Headband
Leggings: Holy Rainbow bottoms
Boots: Highhouse halfboots/best man's gaiters


Let me know if you want to extend this glamour to another class ^^
I forgot what the exact name of the arm part is called but I'll look later on
