I don't if you could call it a 'Girly" website or not but my 15-year-old daughter really likes Club Penguin. It's a kid-friendly site from Disney and membership is only something like $5.95 a month for unlimited play or whatever it is they do.
Are There Any Girly Websites Like Stardoll.com?
A girl would like for her birthday a puppy or a kiss maybe!
