Achievement problem / question

[Xelsiar]

So, I'm trying to just get a few achievement and I run across the newly acquired "Grand Company" achievements. I'm looking through it and see "I make this look good" and I'm like, oh all i gotta do is buy 4 pieces of GC gear to get it.

I buy Lominsan gloves, overcoat, boots, and hat.. and I get no achievement. I bought the easy set which cost 1k seals a piece. If this isn't the set that you are suppose to buy, how are you suppose to know which set it is that you ARE suppose to buy? I just wasted 4k seals, when the names of the pieces of gear I need are have those names in the names of the GC gear I Bought.

I Make This Look Good

Obtain a complete set of Grand Company soldier armor consisting of a soldier's cap, a soldier's overcoat, a pair of soldier's gloves, and a pair of soldier's boots

I bought Lominsan Soldier's Cap, Lominsan Soldier's Overcoat, Lominsan Soldier's Gloves, and Lominsan Soldier's boots.

Could someone shed some light for me?

Edit.
Changed 2nd gloves > boots
