Feather Attached
This is Feather Attached! Like many of these older suits, I cannot find any information on when it was released. It was likely released in late 2017 or early 2018, near the launch of this game. It is available for free once you've reached 300 activity in your Stylist Association.
Your Stylist Association does have to have the suit unlocked and fully crafted, however, so if your guild doesn't have this consider joining a different one. (Sorry.) These suits will be tagged Shadow Workshop, while the other kind of association suits will be tagged Fantasy Workshop.
This suit comes with a posed coat, makeup, and four moveable accessories. That's a lot for a free suit from 2018/2017. I find it quite beautiful, myself. Full breakdown below the cut!
