I have read that it is not just me, and I am relieved. However, I believe that this issue should be addressed and fixed soon. I logged onto Minecraft recently after changing my skin to this cute TV mask bunny girl. It was an Alex model, so when it came to being on the Minecraft website, I selected "slim" (as shown in the screenshot). When I got in the game, it didn't work. I panicked and tried almost everything as it even took me a long time to get here.
