My most recent order from Aerie
Sizing:
XS/small in the green Halloween tee
S in the oversized sweatshirt
XS in the chambray oversized button down
Medium in the blue long sleeve
Small in the soft pink cardi. I think you need to size up to get the look the model is wearing.
XS/small in the cape from the intro. It runs very generous btw
