Anime / Manga similar to Princess Tutu?

[au-revoir.livejournal.com]

Hello!

I just finished the Princess Tutu anime, and I absolutely loved it. So sweet, beautiful, and sad. ;____; ♥

I haven't seen many anime series, or read that much manga, so I was hoping for some recommendations on what to watch and/or read next. Basically, what are your favorite anime and manga that are close in theme to Tutu or that a fan of Tutu might like?

As for me, I had seen Revolutionary Girl Utena before Princess Tutu, and I loved both. I think they share a lot of themes: growing up, unrequited love, princes and princesses, etc.

Thanks!
