hello. i was hoping someone could identify this song.it goes "perfect to me yes you are" or something along that line. the music video has this singer with long hair singing with a white background. i saw it in topshop about half a year back. help is really appreciated. thanks.

It could be 'I'm like a bird' by Nelly Furtado.

The song starts:

You're beautiful, that's for sure
You'll never ever fade
You're lovely but it's not for sure
That I won't ever change
