I know a little bit about of a lot of things. But the one thing I claim expertise in is online makeover and dress up games. I spent the summer working at the library at my university as a student supervisor, which meant that I told people to do shelve books and played dress up games for 6 hours a day. I would feel confident standing before the supreme court and telling them that "Forever: A Wedding Dress-Up game" is the absolute best that there is. Play it on deviant art.
It has a unique menu that allows you to choose each different piece of the dress and they all go together. The artist really solved a lot of the problems that make these games annoying. The second two screen shots are from the only games I could find that are strictly sweater themed. Neither of them is very fun, because you have to drag the the clothing item onto the body and move it around until you get it in the perfect position. Don't even play them, man.
I was really disappointed with the lack of good sweater games. I wish YavMamemo would make a sweater game! She (or he) is the best!
You can play this Sweater Dress Up Game here. But I wouldn't bother.
This one is called Cowl Neck Sweater, and you can play it here. But, probably don't.
Maybe I should learn how to make my own, non?
