Hello! As promised, here's the dress-up tutorial I said I'd make.
It's a pretty basic tutorial, but hopefully it will help someone. ^_^

Just remember there has to be a layer for each thing: one for characters (in wich you can make a little animation), one for clothes, one for BGs, another one for music and so on...

The success of your game depends on your creativity. Good luck! ^_^

FAQ:

Where can I get Flash?
You can download a 30-day free trial here --> [link] (scroll all the way down to find it) or buy it at any software store.

How do I add music to my games?
Click on "File", and then "Import". A window will open. Select the song you want (which you'll find in the file you usually keep your songs) and click ok. Then make a layer called "music" (or something like that) and click in the first key-frame. Finally, open your "properties" panel, and where it says "sound" click on the arrow and choose the imported song file.

When I test my game, sometimes some clothes that should be on top (e.g. jacket) appear below other clothes that should be on the bottom (e.g. t-shirt). Why is that?
Well, that's because you are not bringing your objects (clothes in this case) back and forth as you please. To do so, simply click on the clothe (or group of clothes) you want to bring forward and press Ctrl+G.

Is your hair really blue?!
Huh? N-no, it's not! LOL
