Hmm...
I'd suggest the following:
Whisper of the Heart
Cross Game
Mysterious Girlfriend X
Masion Ikkoku (does have a see-through nightgown in the first episode, shows up again end of season 1, and then never seen again).
Touch
Tonari no Kaibutsu-kun
Ano Hana
Hanasaku Iroha
Mawaru-Penguindrum for a twist. (It's reality, but not reality)
You'd probably enjoy the
story of the literature girl too.
