How to change my minecraft pe skin? What do I use to do so?

I'm Raven. I like minecraft pe. I want to change my skin since I'm a GIRL and not a STEVE. But I don't know how to do that. I think the one app I use doesn't work because everytime I enter my password for my mojang account, it then says I have to purchase the game. But I already did purchase the game. Help me please? P.S. Yeah I know I'm a noob. Don't tell me it's impossible to change a minecraft skin on pocket edition, because I saw a video of someone playing minecraft pe, and they had a Herobrine skin on. Not a Steve skin

Minecraft PE Lite gone or?

Recently I saw my cousin playing the LITE version,

Has anyone on minecraft pe have it crash, than a creepy no name pop up when you get back in?

I was in my mine when it happened. I was smelting ores, when it crashed. When I got back in and everything, I was strangely above ground. When I got back in the mine, I saw a nameless game tag coming down the stairs. I got too scared and haven't played that world since. I've played different worlds with no crashes, or nameless name tags. If someone can help me I would be very grateful.
