Daz'aling Attire

If you don't get this achievement after earning all of the pieces, try double checking to make sure the trade timer is removed from each item.

Because of the way the raid is constructed, it takes a little additional effort to find where your items drop. For example, Blazewing Hood, a constituent part for priest, drops from Jadefire Masters (different boss IDs for horde and alliance) and is just listed as "Boss Drop". It'll take some preparation in order to spend your coins wisely if you're looking to complete your set.
