How do you get a new skin?

The change skin feature is not available in the current version. The game says it is coming soon when you click on the person icon, so hopefully an option to change skin will be here soon.

You can of course change to be male or female by selecting from that option at the bottom of the game menu.

My friends have skins so should i just like update or something

All you have to do is click on the little person icon and click on the skins, if they are locked just do what it says to do, then you will be able to use the skins.

Update your game
