forever21 song

I was at forever21 the other day and i heard this song, she talks during the song saying " i saw you at the bus station with your new girlfriend, she had the scarf i gave you" or something similar like that. it was a girl who sang it. i think its like alternative or something similar to it.

Maybe..

Robyn - Be Mine

I saw you at the station, you had your arm around
What's her name? She had on that scarf I gave you
you got down to tie her laces
