Keep your kids away from this website. While it has many cute and innocent games, inappropriate advertisement pops up while kids are playing. Ex. Ads for the Showtime show "The L Word" showing two women kissing, ads for some of their games showing animated scenes of a couple that although shown from the shoulders up, is clearly having sex by their movements, face expressions and lack of clothes.
I'd would've given this 3 stars (maybe 4), since it's fun, but I don't think the site is always appropriate for tween, (one game had 'sexy' in the title) even though I think most tween girls would want to play dress up games.
One of my sisters one on this website so I decided to go on. Some dress up games seemed innaprorpiate, and I haven't seen innapropriate ads but that's because I just ignore it. I didn't do a lot of exploring on this website, but I don't think it's safe.
