kind of a "Bara no seidou in blue" feel to it.
Mana returning to origins, maybe a klaha return and malice mizer as well, I'm positive.
That shirt does look great
Once a long time ago, I don't remember exactly, but I believe it's no longer in chouchou, called "bat-collar blouse", it was black or dark green. It was 100% polyester too, I personally believe that this fabric is good in the shirts that moitié produces, they are good for work, I at least intend to wear this “bara no seidou” shirt at work lol. I only found this shirt I'm referring to, it's a slightly heavier shirt.
I think this new one has a better fit and is cooler despite everything. Even though it's polyester, it gave me a knit vibe, as if it had something of a sheen to it when exposed to light.
I have a slight hunch that the old Mana was slightly inspired by the Medenius, which launched a short time before, almost on the same model. The Medenius model is called “Winged Blouse”, but it's only available in royal purple, so it looks much lighter than the MmM blouse.
The new MmM blouse comes in two versions, a longer, more casual one and "the man of business" one.
