The new Nomura?

[Carin-Eri]

It's an old meme - Tetsuya Nomura likes to design characters with lots of belts (along with black leather and zippers), sometimes excessively so (Lulu from FFX springs to mind, but also Squall from FFVIII), suggesting Nomura has a thing for them. Yoshi though removed equippable belts from FFXIV back when EW lauched, so... it's a little injoke to an old meme.

Nomura has a reputation of using an obscene amount of belts on his designs (see Lulu from 10 for an example)

I just Googled this Lulu character... and I can see what you mean now! In fact it looks as if her 'skirt' isn't one - it's a collection of belts!
