Who do you think is next?

There already are primal glamour. You can buy them for poetics, the level 60 ilevel 240 ones. There is Hellfire (Ifrit), Slipstream (Garuda), Torrent (Levy) and Hailstorm (Shiva)

Personally I hope they do this again for a tier, for other more recent primals. The warring triad, Lakshmi, etc could be cool.

They could do a tier of gear themed on trials every expansion and probably not run out of material.

Gaius van Baelsar's Garlean armor for both genders. PLEASE? No? Okay...

[Fland]

Guys have: Urianger, Papalymo, Thancred v1, Cid, Thancred v2, Hildibrand, Hien, Aymeric, Gosetsu, Snow and Tidus, for a total of 10 NPC/character outfits unless I'm missing something.
Girls have: Yda, Y'shtola v1, Minfilia v1, Y'shtola v2, Lyse, Edda, Yuna, Lightning, Minfilia v2, Krile, Alma and Y'shtola v3, for a total of 12 NPC/character outfits.

Worth mentioning that while Aymeric's outfit is male only, the girls still have access to the hairstyle.

So guys have 2 hairstyles while girls have 4 (counting Krile's headpiece as one), since Aymeric's hair is available to both.
Safe to assume that at some point we'll be seeing Ryne, Gaia and Lyse's outfits being added due to popular demand, maybe even the hair.

I just wish we had some more interesting male character designs from SE because when you look at Gaia, Y'shtola, Ryne, Lyse and Edda you can easily tell a lot of people would gladly use their outfits because they just look nice, "fashionable" and glamour worthy to be interchangeable with other pieces.
But then you look a Hien, Gotetsu, Gaius, Zenos, Emet and the Exarch and you think "cool, but doesn't really work outsite it's own design, in it's own niche".

The ones you listed count to 11 lol

Personally Hien's is my favorite among the list. I think it's quite nice and fashionable (I also like the color combination). Cid's another one of my faves because it looks good on my character.
Aymeric's, Tidus', Exarch's, and Emet's are also pretty good. Zenos' and Gaius' are intricate but not really my taste.
Snow's, Gosetsu's, and Thancred's v2 are the ones that a bit meh.

But yeah I agree that it'd be nice to have more interesting male attire design. Hopefully we'll get new male NPC with unique attire in ShB relic quest later.

A reworked version of Hien's outfit with higher quality textures and access to his stubble/hairstyle.

I can dream, right?

Female version of Hien’s outfit please.
