I would describe a Disney princesses awakening as slow and delicate, almost graceful.
(EXAMPLE)
She was in an eternal slumber, that's all she could do was sleep, until the spell was broken by me. She was slow, but steady. She seemed as beautiful and as graceful as she was before the curse. (which couldn't be possible)
(ANSWER)
So basically, the princess looks the same as from when she woke up, and in real life, nobody wakes up perfectly, from what I know.
If you need anything else just ask! Sorry if the example was a little bland.
