I logged in and wrote a wall of text, just to realize that the series on my mind that I wanted to nominate was already nominated in the previous round.

Necrobride by RoseSense
This is a "second-chance" shoujo with the lovely historical dresses, written in a way that makes it easy for people to follow along (and I really wanted to learn lots from). The characters are really cute and make you want to root for them, and there is also a slight sense of mystery that leaves you wanting to know more.
