She looks so pretty and mature in these photos, especially where she's wearing those sweaters while recording. She looks very motherly in the best sense.
I'm just loving her glasses and hair combined with the sweater.
Makes her look so human.
Also, her hair in the photos from the shooting of the PV is awesome. Wish I had seen those hairstyles back when I was going to prom so I could've gotten my hair done that way. XD
