Unicorns aren't vain. They're the most beautiful creatures in the universe and just kind of accept it. I asked this one if I could try a braid, and she had honestly in all her life never had her mane braided. She was very patient and sat quite stil for me... I think the mirror intrigued her. She usually sees her reflection, horizontally, in a pool, and to see it vertically was quite a surprise. After the braid was finished she walked around and behind it to inspect it, and tapped it once with her horn. She almost tried to walk through it, and I wouldn't have been surprised to see her walk right into it like Alice, into a world of reflections.
