Need help with new skins

Ok so I’m trying to create my own story and I have seen the nice new skins and hair but when I try to make a character it gives me only the old ones that aren’t exactly appealing to me. I was just wondering is it something I have to update or pay for? or is there a cheat sheet to it? Sorry if it’s obvious and I’m just being silly on finding it but I’m new here and kinda new to the game I literally made this account just to find out how to get these gorgeous skins!

Please and Thank you!!!
