Taaz.com is a very easy to use online service that allows you to give any photo a makeover:

This was the original:

If you look closely (by clicking on the photo to get the full size version), you’ll notice that I’ve applied lipstick, foundation, blush, blue contact lenses, mascara, and of course, changed the hairstyle. For each one of those, there are many different options to choose from. Obviously, the “doctoring” of the photo is very visible, but I did not spend too much time trying to get it just right. I have other things to do.

But, try Taaz.com yourself. You’ll have lots of fun.
