Have you ever tried the My Story is Makeover Game at Lifetime TV? It's one of my favourite dress-up games. It lets you put together a really complete look, with makeup, accessories, hair, and clothes. If you sign up for an account, it let you save the looks you create, and access special features (this is free, by the way!). Every day you log in, if you had saved a look the day before, you earn a special item you can use for the makeover. I've earned loads of cool things like glitter eyeshadow, tattoo sleeves, silk stockings, an iPod, a hot-pink top...and you can see the things I've done right here at my diary! Very cool, no?
Try it out, and you can post your link here and let me see too. :-)
