I don't like those two weird braids on the new hairstyle. Without them it would be fine.
I'm looking forward to the one the new wedding NPC has though. But in the end, I will only be disappointed in it again anyway because the songbird hat, cherry blossoms and other hairpins will only float above the head with it on female Au Ra. There are only like 5 different hairstyles where hair accessories don't float that much.
The biggest problem with that is that when it's locked behind RNG you can't really try out if it would look good on your character and how it clips with things or how much the hairpins float above it.

Where did it say that the second hairstyle will be available in the next Eureka anyway?

Other than that, when can we finally flip hairstyles like facepaint? I'm waiting for that feature ever since I began playing FFXIV.
