Blowsy, yes. Actually, this characterization of her makes total sense to me--I've known a lot of women like this--usually from rich, pampered families. They use the little girl voice, and they are loose because it is an easy way to rebel against Mummy and Daddy and they drink because it loosens them up and signals to guys that they are available. They like the attention because it shows that their charm works on someone other than Daddy. Sounds harsh, but I've seen it over and over.
