It is the singer's first signature fragrance in collaboration with Elizabeth Arden.
And she told how everything from the perfume’s name to the ingredients of the scent are drawn from her personal experiences.
Swift said: “Wearing perfume is such a unique way to create memories. Like songs, a scent can take you back and allow you to relive a moment in time.
“I wrote the lyric, ‘I’m wonderstruck, blushing all the way home’, for the song Enchanted about the first time you meet someone.
“A fragrance can help shape someone’s first impression and memory of you. It’s exciting to think that Wonderstruck will play a role in creating some of those memories.”
