The only thing I can remember is a mirror and a rose in a glass case. I think something came through the mirror. There may also have been a fairy involved. I think it was animated and it was either an 80s or early 90s film.

Sounds like beauty and the beast

I almost included this before, but it is not beauty and the beast. I think there was also a pegasus.

Sailor moon maybe?

The Princess and the Goblin. Her Great Great Grandmother would be the fairy, and there is a stained glass window of a rose that she presses her hand to that disappears and reveals a passageway to the tower where her great great grandmother is. If you remember anything about "following the thread" and stone shoes, than that's the movie

It's probably not the film but Beauty and the Beast has a mirror and a rose in a glass case... a fairy or Gypsy puts a spell on a prince because he is heartless and does not let her stay the night out of the cold... the Gypsy then turns into a beautiful fairy and turns the prince into a beast... to break the spell he has to make someone fall in love with him and he has to fall in love before the last petal falls from the rose which he keeps in a glass case next to a mirror
