Yesterday though I saw a thread about this topic, maybe the achivement is bugged?
At least you should try to talk to the NPC while wearing the set first

Or maybe....you just don't make it look good..
Ahahaha, you are good! I didn't think about talking to the person .. I figured it'd be just like the chocobo sets of barding where you just obtained it and WHAM! You obtained it. I'll finish up this blm chest quest, then i'll head back to LL to see if that is the case.

Thank you for giving some insight.
