I don't know who she is - well, I don't know who most of them are! - but she looks like she's older and trying to make her face look younger by exaggerated make-up and that odd hairstyle. She looks rather old and tired - and also very irritable! Nice dress though.
The makeup is a little too much for my taste with her fair skin. I would have picked a shade of pink. I adore this dress though. Its very cute and the color is perfect.
